Struct wayland_client::protocol::wl_buffer::WlBuffer

pub struct WlBuffer { /* private fields */ }

content for a wl_surface

A buffer provides the content for a wl_surface. Buffers are created through factory interfaces such as wl_shm, wp_linux_buffer_params (from the linux-dmabuf protocol extension) or similar. It has a width and a height and can be attached to a wl_surface, but the mechanism by which a client provides and updates the contents is defined by the buffer factory interface.

If the buffer uses a format that has an alpha channel, the alpha channel is assumed to be premultiplied in the color channels unless otherwise specified.

See also the Event enum for this interface.

Implementations

impl WlBuffer

pub fn destroy(&self)

destroy a buffer

Destroy a buffer. If and how you need to release the backing storage is defined by the buffer factory interface.

For possible side-effects to a surface, see wl_surface.attach.
