Struct KeyEvent 

#[non_exhaustive]
pub struct KeyEvent {
    pub vk: u32,
    pub mods: u32,
    pub down: bool,
    pub repeat: bool,
    pub scancode: u32,
    pub location: u32,
}

(E2) a key as it went down or up, for a canvas that passes the keyboard on (a web page’s keydown / keyup events): ui.key_event_take

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

vk: u32

VK_*

mods: u32

MOD_* at the time

down: bool

down (true) or up

repeat: bool

a down of the system’s auto-repeat while the key is held

scancode: u32

the key’s place on the keyboard, whatever the layout: Windows’ scan code (0xE0.. for extended keys), Linux’s evdev code; 0 where the platform does not tell (macOS, the browser, Android)

location: u32

KL_STANDARD, KL_LEFT / KL_RIGHT (the two Shift, Ctrl, Alt, Windows keys), KL_NUMPAD
