You can view the docs here.

Example - Blink

let mut mcp = MCP23017::new(0x20, 1).unwrap();
let led = Pin::new(0).unwrap();
mcp.pin_mode(&led, Mode::Output).unwrap();

loop {
    mcp.output(&led, State::High).unwrap();
    sleep(Duration::from_millis(200));
    mcp.output(&led, State::Low).unwrap();
    sleep(Duration::from_millis(200));
}
