Struct wayland_client::wayland::shm::WlShm

pub struct WlShm {
    // some fields omitted
}

shared memory support

A global singleton object that provides support for shared memory.

Clients can create wl_shm_pool objects using the create_pool request.

At connection setup time, the wl_shm object emits one or more format events to inform clients about the valid pixel formats that can be used for buffers.

Methods

impl WlShm

fn create_pool(&self, fd: RawFd, size: i32) -> WlShmPool

create a shm pool

Create a new wl_shm_pool object.

The pool can be used to create shared memory based buffer objects. The server will mmap size bytes of the passed file descriptor, to use as backing memory for the pool.
