Enum DisplayBacklightRequest

pub enum DisplayBacklightRequest {
    SetMinimumRgb {
        minimum_rgb: u8,
        responder: DisplayBacklightSetMinimumRgbResponder,
    },
}

Manipulates global policy for display backlight. Serves as the main “front end” interface for usage by UX components; other protocols (such as fuchsia.ui.scenic.Session and fuchsia.hardware.display.Controller) act as implementation.

Global Scope. All displays, in all display controllers, are affected uniformly.

Effect Timing. This protocol does not guarantee a deadline by which the minimum value is applied to a display; it is best effort.

Multiple clients. This protocol does not guarantee unique access to manipulate display backlight functionality.

Reference. Related to fuchsia.hardware.display.Controller.

Variants

SetMinimumRgb

Submits a new minimum color channel value for display backlight.

The valid range for a minimum value is [0, 255] (inclusive). For a new minimum value M, each color channel’s range will be limited to [M, 255].

Flow control: The caller is allowed at most one in-flight |SetMinimumRgb| at at time. Subsequent calls must wait until the acknowledgment returns. Non-compliance results in channel closure.

Fields

minimum_rgb: u8

responder: DisplayBacklightSetMinimumRgbResponder
