Struct KeyEvent 

pub struct KeyEvent {
    pub key: String,
    pub modifiers: u8,
}

Fields

key: String

The key’s name, in the web KeyboardEvent.key vocabulary every platform can map onto: the four arrows (“ArrowLeft”, “ArrowRight”, “ArrowUp”, “ArrowDown”) and the ten digits (“0” through “9”, from the main row or the numeric keypad) everywhere, plus “Delete” and “Backspace” on backends with no menu bar (Cap::AppMenu unsupported), where no accelerator can own those keys. A focused piece claims every key the route carries, so offering them on a menu-bar platform would let a canvas swallow the Delete its own Edit menu was about to act on (docs/menus.md). The two delete keys keep the names the platform gives the physical keys (a Mac’s ⌫ is “Backspace” and its ⌦ is “Delete”), so a handler that means “remove this” takes both. A digit arrives only while neither KeyEvent::PRIMARY nor KeyEvent::ALT (nor a Mac’s Control) is held: ⌘1 and Ctrl+1 are accelerators, and a canvas claiming them would starve the menu. Most backends name the digit the keypress types, so a layout whose number row needs Shift for digits reports “1” with KeyEvent::SHIFT set; XAML and ArkUI read the physical key. Backends emit Event::Key only while no text widget has focus; a field’s own editing keys never surface here.

modifiers: u8

A KeyEvent::SHIFT/KeyEvent::PRIMARY/KeyEvent::ALT mask.

Implementations

impl KeyEvent

pub const SHIFT: u8 = 1

pub const PRIMARY: u8 = 2

The platform’s command key: ⌘ on Apple platforms, Ctrl elsewhere (the Shortcut::primary convention).

pub const ALT: u8 = 4

pub const DIGITS: [&'static str; 10]

The ten digit key names, indexed by value.

pub fn digit_name(c: char) -> Option<&'static str>

The key name for a typed character when it is one of the ten digits: what a backend reports for a keypress that types 0–9.

pub fn digit(&self) -> Option<u8>

The value of a digit key, or None for every other key.

pub fn shift(&self) -> bool

pub fn primary(&self) -> bool

pub fn alt(&self) -> bool
