Expand description

Which key is pressed. Not all of these are probable to appear on most systems. A lot of this list is @wez trawling docs and making an entry for things that might be possible in this first pass.

Implementations§

Source§

impl KeyCode

Source

pub fn normalize_shift_to_upper_case(self, modifiers: Modifiers) -> KeyCode

if SHIFT is held and we have KeyCode::Char(‘c’) we want to normalize that keycode to KeyCode::Char(‘C’); that is what this function does. In theory we should give the same treatment to keys like [ -> { but that assumes something about the keyboard layout and is probably better done in the gui frontend rather than this layer. In fact, this function might be better off if it lived elsewhere.

Source

pub fn is_modifier(self) -> bool

Return true if the key represents a modifier key.

Source

pub fn encode( &self, mods: Modifiers, modes: KeyCodeEncodeModes, is_down: bool, ) -> Result<String, Error>

Returns the byte sequence that represents this KeyCode and Modifier combination,
