Struct Leds 

#[non_exhaustive]
pub struct Leds {
    pub caps_lock: bool,
    pub num_lock: bool,
    pub scroll_lock: bool,
}

The lock state, as the keyboard’s lights would show it.

Two sides use this and neither owns it: xkb tracks the latch, and the device carries the light. Keeping them together is the caller’s job – read Keyboard::leds after a key, and when it differs from last time push it to Seat::set_leds.

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.

caps_lock: bool

Caps Lock.

num_lock: bool

Num Lock.

scroll_lock: bool

Scroll Lock.

Dead on most layouts: xkb’s default compat has no mod-mapping for <SCLK>, so nothing sets it and Keyboard::set_leds cannot make it true.
