Rustのwasm32-wasip2に関するPull requests, Crates, Cargo.tomlとか集めるスレ
黒ヰ樹Why
Rust Version 1.82.0 (2024-10-17)にPromote wasm32-wasip2 to Tier 2.がきたのでaxumをWASMで動かすための情報収集をしたい。
自力でaxumをWASMで動かせるようになったらクローズ予定。
Pull requests
mioがwasm32-wasip2サポートしたらtokioもwasm32-wasip2サポート予定。
socket2の
The wasm32-wasip2 target will be a tier 2 target starting with Rust 1.82 and will gain improved socket support in Rust 1.83, so it felt like it made sense to add support for WASIp2 now.
はこのPull requestsのことっぽい。
httpはwasi Crates使う予定なさそう。
現時点でhyper, axumはPull requestsなさそう。
Crates
getrandomは使える。
chronoも使える？
WASI専用のHTTPリクエストクライアント&Webサーバーライブラリ。
wasm32-wasip2で使える。
leptosはwasm32-wasip2サポート予定。
Cargo.toml
数ヶ月前まではlibc, socket2, tokio, hyper, reqwestのPatchを作っていた。
