## Usage

```rust
let mut headers = [httparse::EMPTY_HEADER; 64];
let mut req = httparse::Request::new(&mut headers);

let buf = b"GET /index.html HTTP/1.1\r\nHost";
assert!(req.parse(buf)?.is_partial());

// a partial request, so we try again once we have more data

let buf = b"GET /index.html HTTP/1.1\r\nHost: example.domain\r\n\r\n";
assert!(req.parse(buf)?.is_complete());
```
