Module buffer 

Wayland Buffer and SHM Pool Management

Provides pixel buffer allocation backed by kernel-heap memory pools. Each WlShmPool owns a contiguous byte allocation from which individual WlBuffer objects are sub-allocated at arbitrary offsets. This mirrors the real Wayland wl_shm / wl_shm_pool / wl_buffer protocol objects.

Structs

Buffer

Legacy buffer struct retained for surface.rs compatibility. New code should use WlBuffer + pool references.

WlBuffer

A buffer object referencing pixel data within a WlShmPool.

WlShmPool

A shared memory pool that backs one or more buffers.

Functions

init_shm_pools

Initialize the SHM pool registry (called once during Wayland init).

register_pool

Register a new SHM pool.

unregister_pool

Remove a pool from the registry.

with_pool

Execute a closure with read-only access to a specific pool.

with_pool_mut

Execute a closure with mutable access to a specific pool.
