rayon-wasm
is an unofficial forked publication, as noted here: #1019 (comment). Please use rayon 1.7.0.
That wasm support is just a fallback that lets rayon work single-threaded, but that's only applied when you leave num_threads
unspecified. The target does not support threads, so std::thread::spawn
is returning Unsupported
.
With Rust nightly, you can build a version of the target with atomics, and threading may work. See the documentation here: https://github.com/GoogleChromeLabs/wasm-bindgen-rayon
There are also proposals in motion to add real supported WASI threading: rust-lang/compiler-team#574, rust-lang/compiler-team#607, rust-lang/compiler-team#661.
