Struct Layout 

pub struct Layout {
    pub name: &'static str,
    pub entries: &'static [Entry],
    pub decimal_separator: char,
}

A keyboard layout: a table of positions, and the decimal key’s character.

Fields

name: &'static str

Human-readable name, for logging what a device is being read as.

entries: &'static [Entry]

Positions, in no particular order. Looked up by linear scan: about fifty comparisons, at most a few times per second, against the complexity of keeping a sorted table sorted.

decimal_separator: char

What the numpad’s decimal key types. . in most of the world, , in most of Europe.

Implementations

impl Layout

pub fn entry(&self, code: KeyCode) -> Option<&'static Entry>

What this layout puts on one position, at each of its four levels.

None for a position no layout describes. Positions the layout does not list fall back to the shared letter table, so a layout only spells out what it moves — which is why Layout::entry answers for KeyCode::A on a table that never mentions it.

An on-screen keyboard reads this to letter its keys: the caller picks the level from the modifiers it is currently showing.
