macro_rules! key {
($($tt:tt)*) => { ... };
}
Expand description
check and expand at compile-time the provided expression into a valid KeyEvent.
For example:
let key_event = key!(ctrl-c);
is expanded into (roughly):
let key_event = crossterm::event::KeyEvent {
modifiers: crossterm::event::KeyModifiers::CONTROL,
code: crossterm::event::KeyCode::Char('c'),
};
Keys which can’t be valid identifiers or digits in Rust must be put between simple quotes:
let ke = key!(shift-'?');
let ke = key!(alt-']');
