const reference to a |::fidl::ClientEnd

::fuchsia_ui_policy::DisplayBacklight>|,

avoiding setting up a client.

Public Methods

::fidl::WireResult< ::fuchsia_ui_policy::DisplayBacklight::SetMinimumRgb> SetMinimumRgb (uint8_t minimum_rgb)

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.

Allocates 40 bytes of message buffer on the stack. No heap allocation necessary.
