WASM/Rust for stdlib Native Extensions?

[rrichardson]

Is there a way, or could there easily be a way to extend the stdlib using WASM and/or Rust?

Yep, it is available via api:

jrsonnet/crates/jrsonnet-evaluator/src/lib.rs

Line 431 in ce2d8d5

pub fn add_native(&self, name: Rc<str>, cb: Rc<NativeCallback>) {

But no such functionality for standard CLI. I can implement it, but i dont think it will be useful. Vanilla jsonnet also doesn't supports it (But there is existing issue: google/jsonnet#206)
