   1 //! Raw API bindings to the WebAssembly System Interface (WASI)
   2 //!
   3 //! This crate provides Rust API bindings to WASI APIs. All WASI APIs are
   4 //! exported from this crate and provided with the appropriate type signatures.
   5 //! This crate is entirely procedurally generated from the `*.witx` files that
   6 //! describe the WASI API.
   7 //!
   8 //! # WASI API Version
   9 //!
  10 //! The WASI API is evolving over time. It is both gaining new features as well
  11 //! as tweaking the ABI of existing features. As a result it's important to
  12 //! understand what version of this crate you're using and how it relates to
  13 //! the WASI version of the spec.
  14 //!
  15 //! The WASI specification is organized into phases where there is a snapshot
  16 //! at any one point in time describing the current state of the specification.
  17 //! This crate implements a particular snapshot. You can find the snapshot
  18 //! version implemented in this crate in the build metadata of the crate
  19 //! version number. For example something like `0.9.0+wasi-snapshot-preview1`
  20 //! means that this crate's own personal version is 0.9.0 and it implements the
  21 //! `wasi-snapshot-preview1` snapshot. A major release of this crate (i.e.
  22 //! bumping the "0.9.0") is expected whenever the generated code changes
  23 //! or a new WASI snapshot is used.
  24 //!
  25 //! # Crate Features
  26 //!
  27 //! This crate supports one feature, `std`, which implements the standard
  28 //! `Error` trait for the exported [`Error`] type in this crate. This is
  29 //! enabled by default but can be disabled to make the library `no_std`
  30 //! compatible.
