Struct runa_wayland_protocols::wayland::wl_buffer::v1::events::Release

pub struct Release {}

compositor releases buffer

Sent when this wl_buffer is no longer used by the compositor. The client is now free to reuse or destroy this buffer and its backing storage.

If a client receives a release event before the frame callback requested in the same wl_surface.commit that attaches this wl_buffer to a surface, then the client is immediately free to reuse the buffer and its backing storage, and does not need a second buffer for the next surface content update. Typically this is possible, when the compositor maintains a copy of the wl_surface contents, e.g. as a GL texture. This is an important optimization for GL(ES) compositors with wl_shm clients.

Implementations

impl Release

pub const OPCODE: u16 = 0u16

Trait Implementations

impl Clone for Release

fn clone(&self) -> Release

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Release

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a> Deserialize<'a> for Release

fn deserialize(data: &'a [u8], fds: &'a [RawFd]) -> Result<Self, Error>

Deserialize from the given buffer. Returns deserialized message, and number of bytes and file descriptors consumed, respectively.

impl PartialEq<Release> for Release

fn eq(&self, other: &Release) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for Release

fn serialize<Fds: Extend<OwnedFd>>(self, buf: &mut BytesMut, fds: &mut Fds)

Serialize into the buffered writer. This function returns no errors, failures in seializing are generally program errors, and triggers panicking.

fn len(&self) -> u16

How many bytes will this message serialize to. Including the 8 byte header.

fn nfds(&self) -> u8

How many file descriptors will this message serialize to.
