+## 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());
+```
