A safe Rust API for using [`SetWinEventHook`](https://learn.microsoft.com/en-us/windows/win32/api/winuser/nf-winuser-setwineventhook), powered by the [`windows`](https://crates.io/crates/windows) crate.

## Usage


To use `win_event_hook`, add the following to your `Cargo.toml`:

```toml
[dependencies]
win_event_hook = "0.1"
```

Then create a configuration and install a hook, for example:

```rust
use win_event_hook::events::{Event, NamedEvent};

// create our hook config
let config = win_event_hook::Config::builder()
    .skip_own_process()
    .with_dedicated_thread()
    .with_events(vec![
        // to see these, try right clicking
        Event::Named(NamedEvent::ObjectShow),
        Event::Named(NamedEvent::ObjectHide),
        // to see this, try moving around the cursor
        Event::Named(NamedEvent::ObjectLocationChange),
    ])
    .finish();

// and our handler
let handler = |ev, _, _, _, _, _| {
    println!("got event: {:?}", ev);
};

// install the hook
let hook = win_event_hook::WinEventHook::install(config, handler)?;
```

When `hook` is [dropped](https://doc.rust-lang.org/std/ops/trait.Drop.html), an uninstall is attempted automatically. Uninstallation may fail - to handle failures, instead call [`uninstall`](https://docs.rs/win_event_hook/latest/win_event_hook/struct.WinEventHook.html#method.uninstall) yourself, for example:

```rust
// building on the above example

// uninstall the hook
hook.uninstall()?;
```
