Thegeneric trait object that represents stdio now has the ability toacquire either a p2 stream or an async-based stream. The acquisition ofp2 has a default implementation so in the future this can be primarily`Async{Read,Write}`-based.Many trait implementations and types and such were all consolidatedtogether into the `wasmtime_wasi::cli` module. One-off implementationsin p2/p3 are now shared in one location and `WasiCtxBuilder` no longerneeds any generics for different stdio streams.Functionally this necessitated the addition of `Async{Read,Write}`implementations for some "base" implementations of stdio primitives.Implementations were mostly trivial except for a few adapters which weresignificantly more complicated, namely the `Async{Read,Write}Stream`adapter which converts a single `Async{Read,Write}` into the stdio of acomponent.Finally the stdin implementation for p3 was refactored to avoid use of`tokio::io::stdin()` which generally isn't safe to use. It's replacedwith a custom `AsyncRead` using the worker thread implementation we havein the crate already.Eventually I hope to remove the distinction between `p{2,3}::WasiCtx`and have these be the same type. This will make it nicer to only have asingle `WasiView` trait and additionally make it easier tosimultaneously implement all of WASIp{1,2,3}.* Fix build of C API* Fix build of `wasmtime serve` List of files: /wasmtime-44.0.1/crates/wasi/src/cli/empty.rs Fri, 01 Aug 2025 23:40:08 +0000 Alex Crichton <alex@alexcrichton.com>
