Struct wasi_common::WasiCtx

pub struct WasiCtx(_);

An Arc-wrapper around the wasi-common context to allow mutable access to the file descriptor table. This wrapper is only necessary due to the signature of fd_fdstat_set_flags; if that changes, there are a variety of improvements that can be made (TODO: https://github.com/bytecodealliance/wasmtime/issues/5643).
