Enum BacklightChange 

pub enum BacklightChange {
    Enabled(bool),
    Automatic(bool),
    Level(u8),
    PowerSave(bool),
}

One change to a keyboard backlight, written to the keyboard’s own memory.

Crosses the agent↔GUI IPC, where serde encodes the variant index, so variant order is wire format — changes require a PROTOCOL_VERSION bump (guarded by openlogi-ipc/tests/wire_format.rs).

Variants

Enabled(bool)

Turn the backlight system on or off.

Automatic(bool)

Let the ambient-light sensor choose the level (true), or hold the level the keyboard shows now (false), so nothing visibly changes.

Level(u8)

Hold this level, 0 (off) up to BacklightState::nb_levels minus one. Leaves automatic mode.

PowerSave(bool)

Turn battery saving on or off.
