Enum wayland_protocols_wlr::gamma_control::v1::generated::client::zwlr_gamma_control_v1::Request

#[non_exhaustive]
pub enum Request<'a> {
    SetGamma {
        fd: BorrowedFd<'a>,
    },
    Destroy,
}

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.

SetGamma

set the gamma table

Set the gamma table. The file descriptor can be memory-mapped to provide the raw gamma table, which contains successive gamma ramps for the red, green and blue channels. Each gamma ramp is an array of 16-byte unsigned integers which has the same length as the gamma size.

The file descriptor data must have the same length as three times the gamma size.

Fields

fd: BorrowedFd<'a>

gamma table file descriptor

Destroy

destroy this control

Destroys the gamma control object. If the object is still valid, this restores the original gamma tables.

This is a destructor, once sent this object cannot be used any longer.
