## Generate Rust bindings for Windows

Update: the `riddle` tool is no longer being updated. You can continue to use the [windows-bindgen](https://crates.io/crates/windows-bindgen) library crate directly.

The [riddle](https://crates.io/crates/riddle) tool automatically generates Rust bindings from Windows metadata.

* [Getting started](https://kennykerr.ca/rust-getting-started/)
* [Samples](https://github.com/microsoft/windows-rs/tree/0.58.0/crates/samples)

Start by installing `riddle`:

```
> cargo install riddle
```
