Build errors in my crates (possibly due to 2018 edition?)

[Kimundi]

I'm getting build errors for a collection of crates a recently published. The errors seem to imply that doc.rs does not pick up the cargo feature for the 2018 Rust edition yet.

Is this an not-yet-implemented bug of doc.rs, or is this considered functionality that will not be supported until its stable?

Update: The issue still exists, but I've worked around it for now by going back to the 2015 edition.

Yes, the rustdoc compiler version is 1.28. I think it is in stable channel, which miss rust 2018 support for the time being. Any idea how to force nightly rustc in docs.rs like 1.30?

It would be good to see this working. 2018 is awesome and I want to use it with rustdoc

Looks like its using a nightly, but its pinned to nightly-2018-06-03, prior to any edition support:

https://github.com/onur/docs.rs/blob/09d4ed5d49e6e7243320fa3888bdc6c6acde28b4/Vagrantfile#L50

Actually, its stranger than that. Recent docs.rs failures include a log showing the following versions.

https://docs.rs/crate/futures-preview/0.3.0-alpha.8/builds/121935

$ rustc --version
rustc 1.28.0-dev (b9bf4f162 2018-06-02)
$ cratesfyi --version
cratesfyi 0.5.0 (579f83b 2018-03-05)

Where the rustc sha matches the merge: onur/rust@b9bf4f162.
Which has rust-lang/rust@edae1cc3 as the rust-side parent being merged.

So rustc 1.28.0-nightly (4ecf12bf0 2018-06-02) is a close approximation which can still be installed with rustup (e.g. rustup install nightly-2018-06-03) to test cargo doc` behavior. Note this is 2 months before a stable channel 1.28 was released before the edition feature of cargo became stable.

Since #243 has been merged, docs.rs is using a version of Cargo that can use the edition feature and config item. I've also manually rebuilt greenwasm's docs for version 0.3.1: https://docs.rs/greenwasm/0.3.1/greenwasm/

Seems like this can be closed then, right?

Looks like it!
