Rewrite for the v1 API - #2
Conversation
Edition 2024, MSRV 1.85, reqwest 0.13 on rustls, pinned toolchain and committed lockfile. The committed openapi.json is the source of truth for every wire shape, drift-checked against the backend in CI. Legacy sources removed; the endpoints they called no longer exist.
Auth injection, jittered backoff capped at 8s honoring both legal Retry-After forms, method-aware retry rules so POST never replays where the server may have done work, and error mapping that never promotes a non-envelope body into the message. Content-Disposition filenames are reduced to safe bare names before callers see them.
Consuming builders ending in send(), tri-state PATCH via Patch<T>, lazy Page/stream pagination, streaming exports with the two distinct export routes, ETag-cached emoji catalogue, public stats and previews, and raw typed passthroughs for endpoints the SDK does not cover yet.
PKCE S256 helpers, device-code exchange, and a self-refreshing session with single-flight rotation, proactive expiry refresh, an on_refresh persistence hook, and a typed SessionExpired for dead refresh tokens.
Exact request bodies for create/update/bulk/claim, tri-state PATCH serialization, retry sequencing with Retry-After, hostile export filenames, ETag revalidation, and a stampede test proving concurrent requests share a single token rotation.
The README doubles as the crate docs so its examples compile in CI. MIGRATION.md maps every 0.1.x call to its 0.2.0 shape. License moves to MIT for the rewrite; 0.1.x releases remain Apache-2.0 and the original crate's author stays credited.
fmt, clippy with warnings denied, nextest on stable and the MSRV, doctests, feature matrix, wasm32 check, cargo-deny, semver-checks, docs build, and spec drift against the backend's openapi.json. Publishing runs on GitHub release via crates.io trusted publishing.

Inline comments:
In `@Cargo.toml`:
- Line 33: Update the reqwest dependency declaration to remove the unsupported
webpki-roots feature while retaining the rustls feature and all other existing
features.
In `@examples/sign_in_with_spoo.rs`:
- Around line 14-28: Update the sign-in example to retain the generated state
value, pass that same value to authorization_url, and compare it with the state
returned by the callback before exchanging the code. Reject or otherwise stop
processing when the values differ, preserving the existing successful exchange
flow for matching state.
Apply the same fix in `@README.md` around lines 240 - 249: The README flow has the
same missing state retention and callback validation.
In `@README.md`:
- Around line 27-33: Update README.md lines 27-33 to state that the install
command covers only the SDK and document the companion crates required by the
examples: reqwest 0.13, chrono, futures-util, and serde with the derive feature.
Add each dependency near its relevant snippet at lines 54-60, 73, 121-123, and
293-296, without changing the example behavior.
- Around line 169-170: Update README.md lines 169-170 to limit the documentation
claim to protection against filename path traversal, removing any implication
that the predictable temporary destination is secure. In examples/analytics.rs
lines 35-42, use a securely created temporary directory or file and keep its
handle alive throughout export writing.
In `@src/client.rs`:
- Around line 223-233: Update ClientBuilder::build to parse base_url with
reqwest::Url and reject any parse failure as Error::Config, replacing the
scheme-prefix check. Preserve successful validation for usable HTTP and HTTPS
URLs and include the invalid value or parse error in the configuration message.
- Around line 257-266: Update ClientBuilder::build and build_unchecked to
construct reqwest clients through reqwest::Client::builder().build(), mapping
construction failures to Error::Config instead of allowing a panic from
reqwest::Client::default(). Propagate the fallible result through Client::new
and Client::anonymous, or otherwise eliminate their infallible panic path while
preserving existing configuration behavior.
In `@src/http.rs`:
- Around line 238-254: Update backoff_delay to cap server-supplied retry_after
waits at the existing 8-second maximum; when the supplied duration exceeds that
bound, skip the retry and return the 429 response so Error::retry_after exposes
the server value to the caller.
- Around line 212-221: Update retryable_transport to use a wasm32-safe
is_connect value: set it to false on wasm32 and otherwise derive it from
err.is_connect(), then use that value in both the idempotent and non-idempotent
branches. Preserve retries for idempotent timeout/request errors and the
existing non-idempotent connect-only behavior on supported targets.
In `@src/oauth.rs`:
- Around line 62-100: Replace the derived Debug implementations for TokenPair
and DeviceTokens with manual redacted implementations using
finish_non_exhaustive, matching the existing Client and Session pattern; ensure
access_token and refresh_token are never included in debug output while
preserving Debug support for both types.
- Around line 289-302: Update the on_refresh documentation to state that the
callback must be non-blocking because rotate_locked invokes it while the session
mutex is held; advise callers to offload synchronous persistence rather than
blocking the async executor. Keep the existing hook behavior and scope
unchanged.
- Around line 50-60: Update the OAuth dependency configuration to enable
getrandom’s wasm_js feature for the wasm32-unknown-unknown target used by the
oauth feature, allowing random_string to build with rand 0.9; do not add
RUSTFLAGS or unrelated RNG changes.
In `@src/resources/emoji.rs`:
- Around line 81-107: Update fetch_with_etag to issue the conditional request
through Transport::send rather than transport.http, using its supported
request-building path to preserve authentication, retries, and timeouts while
retaining the existing If-None-Match header and 304 cache handling.
In `@src/resources/links.rs`:
- Around line 486-503: Percent-encode every caller-supplied URL path segment
before constructing request paths in Links::get, Links::get_by_address,
Links::set_status, Links::delete, and UpdateLinkBuilder::send; preserve path
separators while ensuring characters such as ?, #, and / within id, domain, or
alias remain data rather than altering the request target.
In `@tests/stats.rs`:
- Around line 54-57: Update the filters matcher in the affected test to avoid
depending on JSON key order: replace the exact string matcher with a custom
wiremock::Match implementation that reads the filters value from
request.url.query_pairs(), parses it with serde_json, and compares the resulting
JSON object to the expected filters object.

Included review availability: Your plan provides up to 1 included review per hour; 0 remain after this review.
The stats filters map is now a BTreeMap so the serialized JSON has a deterministic key order. On wasm32 reqwest exposes no error classification, so transport failures surface immediately instead of calling methods that do not exist on that target.
The field's only read sits behind a native-target cfg, so wasm builds flagged it as dead code under denied warnings.
rand needs getrandom, and on wasm32 getrandom 0.3 requires the wasm_js feature plus a backend cfg set by the final binary. The feature is now enabled on the wasm target and CI checks the combination the way a consumer would build it; the README documents the RUSTFLAGS line.

Reviewed at c18d4a2. This is the strongest of the four SDKs, and it isn't close — every correction from the plan review landed, is implemented rather than gestured at, and is covered by a test asserting wire bytes. Verified locally: cargo test --all-features passes (9 transport tests, 13 doctests compiled from the README) and cargo clippy --all-features --all-targets -- -D warnings is clean.
One finding is worth holding the merge for, because it's cheap now and expensive once 0.2.0 is on crates.io with an unqualified wasm claim in the README.
Blocker: the crate panics on the wasm32 target it advertises
Cargo.toml:37 declares chrono with default-features = false, features = ["serde", "clock"], which drops wasmbind — one of chrono's defaults. Verified against the vendored source (chrono-0.4.45/src/offset/utc.rs:89-99): the Utc::now() body is selected by
#[cfg(not(all(target_arch = "wasm32", feature = "wasmbind", not(any(emscripten, wasi, linux)))))]
pub fn now() -> DateTime<Utc> {
let now = SystemTime::now().duration_since(UNIX_EPOCH).expect(...);Without wasmbind, wasm32-unknown-unknown compiles to the SystemTime::now() branch, where std panics with "time not implemented on this platform". The js_sys::Date branch is only reachable with the feature on.
Three live paths, all in the error/retry path where an SDK least wants to abort:
src/http.rs:260—backoff_delaycallsstd::time::SystemTime::now()directly for jitter, on every retry attempt. The wasm cfg deliberately keeps status-based retries enabled (retryable_transportreturnsfalseon wasm, butretryable_statusstill applies), so any 408/429/500/502/503/504 reaches this line.src/http.rs:247and:346—retry_after_headerandparse_rate_limitcallUtc::now()whenever aRetry-Afterheader is present, i.e. exactly on 429/503.src/oauth.rs:306—Utc::now().timestamp()on every expiry check, so withoauththe proactive-refresh decision panics on the first authenticated request.
What makes this worth calling a blocker rather than a bug is that both of the crate's own guards are structurally unable to see it:
# is lexical. The panic lives in chrono and std, selected by acfg, so the lint is silent and the "this crate does not panic" claim is unearned on that target.- The wasm gate is
cargo check --target wasm32-unknown-unknown(ci.yml:73-74). It compiles and never executes, so no amount of CI on that job can catch a runtime panic.
README.md:21 says "wasm32 supported" with no qualifier.
Fix:
- Add
wasmbindto chrono's features. - Replace the
SystemTime::now()jitter with something wasm-safe — oncewasmbindis on,Utc::now().timestamp_subsec_nanos()works, or drop clock-based jitter for a process-lifetimeAtomicU64counter, which is cheaper and more predictable anyway. - Make the gate mean something: a
wasm-bindgen-testcovering one retry and one 429 under a headless runner. If that's more machinery than it's worth right now, the honest alternative is softeningREADME.md:21to "compiles for wasm32" until a runtime test exists.
The getrandom fix in c18d4a2 is the same class of problem, caught one dependency over — which is a good argument for the runtime test rather than another round of feature archaeology.
Should-decide: Apache-2.0 → MIT on a repo carrying rdni's history
LICENSE was replaced wholesale in 4310184, and Cargo.toml:17 now reads license = "MIT" while authors still lists rdni. The PR body is right that published 0.1.x stays Apache-2.0 — that can't change retroactively.
Two things worth settling explicitly rather than by inference:
- The plan said "LICENSE stays Apache-2.0" under repo hygiene. Deviating is fine, but it should be a recorded decision, not a line in a docs commit.
- Apache-2.0 → MIT removes the patent grant rdni's contribution carried. For genuinely new code spoo.me can pick any license; for any surviving line of rdni's it needs their agreement. The plan already recommends inviting rdni to review — worth getting an explicit "fine with MIT" in that thread while they're there.
The direction is right: this aligns Rust with spoo-go, spoo-ts and spoo-py, which all declare MIT.
Should-fix
An honored Retry-After is uncapped. src/http.rs:254-257 returns the server's value verbatim, so Retry-After: 86400 parks the task for a day inside the retry loop. The per-request timeout covers attempts, not the waits between them, so one call's total wall-clock is unbounded and nothing in the crate bounds it.
This is a shared gap — TS, Go and Py are all uncapped too, so it isn't a Rust regression. But Rust is where the precedent can be set, and commitment #6 ("types carry meaning… retry-after is a Duration") is about making time explicit rather than implicit. Suggest capping the honored wait (60s is generous against a limiter that reports seconds) and letting anything beyond it surface as the rate-limit error for the caller to schedule.
openapi.json ships inside the published crate. Cargo.toml:13 includes it — 489 KB pulled on every cargo add and every docs.rs build, for a file only the drift-check CI job reads. Committing it to the repo is right; packaging it isn't. Drop it from include.
Nits
sanitize_filenametreats two safe cases differently:../../../evil.json→evil.json(basename taken),/tmp/absolute-evil.json→ the fallback. Both are safe, but a caller can't predict which they get. Taking the basename in both is one less rule to explain.- Windows edges the function doesn't cover: a drive-relative
C:evil.jsonhas no separator so it passes through and resolves against that drive's cwd, and reserved device names (CON,NUL,COM1) pass. Marginal for stats exports, but this is the one function that promises safety. src/http.rs:259— the "cheap jitter without a rand dependency" comment doesn't say whyrandisn't available (it'soauth-gated). Without that, the next reader's obvious move is to add it to the default feature set.
What's notably good
- Every plan correction landed, and I checked each against source rather than the PR body. Per-link export is a distinct call (
/api/v1/export/links/{}) rather than aggregateurl_idslicing — the mistake all three siblings shipped.sanitize_filenameexists with a hostile-input table covering../, absolute, backslash,..,.and empty.parse_retry_afterhandles integer-seconds and RFC 2822 dates. PKCE deps sit behind a default-offoauthfeature. - The transport-error retry rule is the strictest of the four.
retryable_transport(src/http.rs:215-224) gates on method and separates "connect error, nothing was sent" from ambiguous failures, so a POST only replays when it provably never left the client. TS and Py gate on method alone; Go reached method-gating only yesterday. Nobody else makes that distinction. - Coverage is complete, including both endpoints the siblings missed —
public/preview(absent in Python) and per-link export (absent in TS). Nothing in scope is unimplemented. Patch<T>is the cleanest null-vs-omit expression in the family, and the pairedpassword()/remove_password()builders mean most callers never name the type. Worth contrasting with Go, where the fields that aren'tOpt[T]are exactly where spoo-cli's silently-no-op--alias ""bug lives — a partial version of this idea is worse than none.- The escape hatch shipped (
client.get/post/patch/delete) with a test asserting it reuses auth and error mapping. Its absence in TS is what forced spoo-raycast into the aggregate-export workaround; this is the first SDK where a coverage gap won't become a downstream bug. map_errorgets the non-envelope case right —HTTP {status}as the message with the raw text preserved onbody, plus theX-Error-Codeheader fallback. Two audit findings pre-fixed before they existed here.- Single-flight rotation behind a
tokio::sync::Mutexwith an actual stampede test spawning concurrent tasks, rather than a comment claiming it.
Merge posture
Nothing ships on merge — crates.io still shows 0.1.1, and the ownership blocker is unresolved (spoo-me still lists rdni as its only owner as of today), so publishing isn't reachable yet regardless. That's the argument for fixing the wasm issue now: it costs two lines and a test today, and costs a yanked release once 0.2.0 is out with "wasm32 supported" in the README.
chrono gains wasmbind so Utc::now() works on wasm; backoff jitter is a process-lifetime counter instead of clock noise; an honored Retry-After is capped at 60s, beyond which the response surfaces with the full wait readable on the error; caller-supplied path segments are percent encoded; the HTTP client builds lazily so construction cannot panic; base URLs are parsed, not prefix-checked; the emoji ETag revalidation rides the normal transport with 304 as a success.
Debug on TokenPair and DeviceTokens prints [redacted] instead of credentials. The on_refresh hook now runs after the session lock is released, so a slow persistence write cannot stall concurrent requests sharing the session.
The oauth example and README verify the echoed state before exchanging the code. The install section lists the companion crates snippets use, the export filename claim is scoped to path traversal, the wasm bullet says compiles-for rather than supported, and openapi.json no longer ships in the published package.
Every endpoint the 0.1.x crate calls was removed in the platform's v1 overhaul, so this is a ground-up rewrite targeting the v1 API. The original crate's design language carries over: consuming builders ending in send(), layered errors, documentation on every public item.
What's here
Tests
47 wiremock tests asserting exact wire bytes (request bodies, tri-state PATCH serialization, retry sequencing, hostile filename handling, a token-rotation stampede test) plus doctests compiled from the README.
Versioning and license
Ships as 0.2.0 with a MIGRATION.md mapping every 0.1.x call to its new shape. The rewrite is licensed MIT; 0.1.x releases remain Apache-2.0. Credit to @rdni for the original crate and the design language this keeps.
