Objective-C interface and runtime bindings in Rust.

Most of the core libraries and frameworks that are in use on Apple systems are
written in Objective-C; this crate enables you to interract with those.

This crate is part of the [`objc2` project](https://github.com/madsmtm/objc2),
see that for related crates, or see [the docs](https://docs.rs/objc2/) for a
more thorough overview.


## Example

```rust
use objc2::ffi::NSUInteger;
use objc2::rc::{Id, Owned};
use objc2::runtime::NSObject;
use objc2::{msg_send, msg_send_id, ClassType};

let obj: Id<NSObject, Owned> = unsafe { msg_send_id![NSObject::class(), new] };

let hash: NSUInteger = unsafe { msg_send![&obj, hash] };
println!("NSObject hash: {}", hash);
```
