//! windows-specific extension for the `wasmtime` crate.

//! This module is only available on Windows targets.

//! 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.
