Enum Request

#[non_exhaustive]
pub enum Request<'a> {
    SetTimestamp {
        tv_sec_hi: u32,
        tv_sec_lo: u32,
        tv_nsec: u32,
    },
    Destroy,
}

Available on crate features staging and client only.

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.

SetTimestamp

Specify time the following commit takes effect

Provide a timing constraint for a surface content update.

A set_timestamp request may be made before a wl_surface.commit to tell the compositor that the content is intended to be presented as closely as possible to, but not before, the specified time. The time is in the domain of the compositor’s presentation clock.

An invalid_timestamp error will be generated for invalid tv_nsec.

If a timestamp already exists on the surface, a timestamp_exists error is generated.

Requesting set_timestamp after the commit_timer object’s surface is destroyed will generate a “surface_destroyed” error.

Fields

tv_sec_hi: u32

high 32 bits of the seconds part of target time

tv_sec_lo: u32

low 32 bits of the seconds part of target time

tv_nsec: u32

nanoseconds part of target time

Destroy

Destroy the timer

Informs the server that the client will no longer be using this protocol object.

Existing timing constraints are not affected by the destruction.

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