Struct BacklightControls 

pub struct BacklightControls {
    pub automatic: bool,
    pub level: bool,
    pub power_save: bool,
}

What software may change on a keyboard backlight beyond turning it on or off, from the 0x1982 capability bits and feature version.

Crosses the agent↔GUI IPC inside BacklightState, so field order is wire format — changes require a PROTOCOL_VERSION bump (guarded by openlogi-ipc/tests/wire_format.rs).

Fields

automatic: bool

Software can switch between the ambient-light sensor choosing the level and holding one (permanent-manual mode): the keyboard supports both.

level: bool

Software can pick the level: permanent-manual mode, 0x1982 version 3 or later, and more than one level.

power_save: bool

The firmware can turn the backlight off on a low battery.

Implementations

impl BacklightControls

pub fn allow(self, change: BacklightChange) -> bool

Whether change is one this keyboard accepts, ignoring the level range: BacklightChange::Level also needs a level below BacklightState::nb_levels.
