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. 31 32 #![no_std] 33 34 mod error; 35 mod lib_generated; 36 pub use lib_generated::*; 37
