//! windows-specific extension for the `wasmtime` crate.
//!
//! This module is only available on Windows targets.
//! It is not available on Linux or macOS, for example. Note that the import path for
//! this module is `wasmtime::windows::...`, which is intended to emphasize that it
//! is platform-specific.
//!
//! The traits contained in this module are intended to extend various types
//! throughout the `wasmtime` crate with extra functionality that's only
//! available on Windows.
