Struct InverseKeymap

pub struct InverseKeymap { /* private fields */ }

Lightweight utility for basic keymap conversion of chars to keystrokes.

This is intended for end-to-end and input testing only; for production use cases and general testing, IME injection should be used instead. Generally a mapping exists only for printable ASCII characters; in particular neither '\t' nor '\n' is mapped in either of the standard zircon keymaps. Furthermore, IME implementations may themselves override the keymap in a way that invalidates this translation.

This is an inverse of hid/hid.h:hid_map_key.

Implementations

impl InverseKeymap

pub fn new(keymap: &Keymap<'_>) -> Self

Creates an inverse keymap from a specialized keymap array. The value of this array at index u, where u is the usage, can be:

• None if the key maps to no char (Esc key)
• Some((c, None)) if the key maps to c, but does not map to any char when shift is pressed
• Some((c, Some(cs))) if the key maps to c when shift is not pressed and to cs when it is pressed

Examples

let _keymap = InverseKeymap::new(&US_QWERTY);

pub fn get(&self, c: &char) -> Option<&KeyStroke>
