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