Struct wayland_server::protocol::wl_buffer::WlBuffer

pub struct WlBuffer { /* fields omitted */ }

Methods

impl WlBuffer

fn release(&self) -> EventResult<()>

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.
