Struct ZwpLinuxBufferReleaseV1

pub struct ZwpLinuxBufferReleaseV1 { /* private fields */ }

Available on crate feature wayland and Linux only.

buffer release explicit synchronization

This object is instantiated in response to a zwp_linux_surface_synchronization_v1.get_release request.

It provides an alternative to wl_buffer.release events, providing a unique release from a single wl_surface.commit request. The release event also supports explicit synchronization, providing a fence FD for the client to synchronize against.

Exactly one event, either a fenced_release or an immediate_release, will be emitted for the wl_surface.commit request. The compositor can choose release by release which event it uses.

This event does not replace wl_buffer.release events; servers are still required to send those events.

Once a buffer release object has delivered a ‘fenced_release’ or an ‘immediate_release’ event it is automatically destroyed.

See also the Event enum for this interface.

impl PartialEq<Weak<ZwpLinuxBufferReleaseV1>> for ZwpLinuxBufferReleaseV1

fn eq(&self, other: &Weak<ZwpLinuxBufferReleaseV1>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
