Documentation
//! Custom platform support in Wasmtime.
//!
//! This module contains an implementation of defining Wasmtime's platform
//! support in terms of a minimal C API. This API can be found in the `capi`
//! module and all other functionality here is implemented in terms of that
//! module.
//!
//! For more information about this see `./examples/min-platform` as well as
//! `./docs/examples-minimal.md`.
