Crate wasmtime_wasi

source ·
Expand description

wasmtime-wasi now supports using multiple snapshots to interface to the same WasiCtx!

wasmtime_wasi::Wasi::new(&Store, WasiCtx) is a struct which owns your WasiCtx and provides linkage to every available snapshot.

Individual snapshots are available through wasmtime_wasi::snapshots::preview_{0, 1}::Wasi::new(&Store, Rc<RefCell<WasiCtx>>).

Re-exports

Modules

  • preview2
    Wasmtime’s WASI Preview 2 Implementation
  • sync
    Re-export the commonly used wasi-cap-std-sync crate here. This saves consumers of this library from having to keep additional dependencies in sync.

Structs

  • Error
  • I32Exit
    An error returned from the proc_exit host syscall.
  • 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).
