wasmer-c-api 1.0.2

// The Wasmer C/C++ header file compatible with the [`wasm-c-api`]
// standard API, as `wasm.h` (included here).
//
// This file is automatically generated by `lib/c-api/build.rs` of the
// [`wasmer-c-api`] Rust crate.
//
// # Stability
//
// The [`wasm-c-api`] standard API is a _living_ standard. There is no
// commitment for stability yet. We (Wasmer) will try our best to keep
// backward compatibility as much as possible. Nonetheless, some
// necessary API aren't yet standardized, and as such, we provide a
// custom API, e.g. `wasi_*` types and functions.
//
// The documentation makes it clear whether a function is unstable.
// 
// When a type or a function will be deprecated, it will be marked as
// such with the appropriated compiler warning, and will be removed at
// the next release round.
//
// # Documentation
//
// At the time of writing, the [`wasm-c-api`] standard has no
// documentation. This file also does not include inline
// documentation. However, we have made (and we continue to make) an
// important effort to document everything. [See the documentation
// online][documentation]. Please refer to this page for the real
// canonical documentation. It also contains numerous examples.
//
// To generate the documentation locally, run `cargo doc --open` from
// within the [`wasmer-c-api`] Rust crate.
