Enum wayland_protocols::wlr::unstable::gamma_control::v1::server::zwlr_gamma_control_v1::Event

#[non_exhaustive]pub enum Event {
    GammaSize {
        size: u32,
    },
    Failed,
}

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

GammaSize

size of gamma ramps

Advertise the size of each gamma ramp.

This event is sent immediately when the gamma control object is created.

Fields of GammaSize

size: u32

Failed

object no longer valid

This event indicates that the gamma control is no longer valid. This can happen for a number of reasons, including:

• The output doesn't support gamma tables
• Setting the gamma tables failed
• Another client already has exclusive gamma control for this output
• The compositor has transferred gamma control to another client

Upon receiving this event, the client should destroy this object.
