Struct Keymap

pub struct Keymap<'a> { /* private fields */ }

A Us Qwerty keymap

Implementations

impl<'a> Keymap<'a>

pub fn apply( &self, key: Key, modifier_state: &impl ModifierChecker, lock_state: &impl LockStateChecker, ) -> Option<KeyMeaning>

Applies the keymap to the given key.

pub fn hid_usage_to_code_point( &self, hid_usage: u32, modifier_state: &impl ModifierChecker, lock_state: &impl LockStateChecker, ) -> Result<u32>

Converts a HID usage for a key to a Unicode code point where such a code point exists, based on a US QWERTY keyboard layout. Returns EMPTY_CODEPOINT if a code point does not exist (e.g. Alt), and an error in case the mapping somehow fails.

pub fn hid_usage_to_code_point_for_mods( &self, hid_usage: u32, shift: bool, caps_lock: bool, ) -> Option<u32>

Trait Implementations

impl AsRef<[Option<KeyLevels>]> for Keymap<'_>

fn as_ref(&self) -> &[Option<KeyLevels>]

Converts this type into a shared reference of the (usually inferred) input type.
