Implementations

impl DmabufParams

pub fn add( &self, fd: BorrowedFd<'_>, plane_idx: u32, offset: u32, stride: u32, modifier: u64, )

Add a plane

In version 4, it is a protocol error if format/modifier pair wasn’t advertised as supported.

modifier should be the same for all planes. It is a protocol error in version 5 if they differ.

pub fn create( self, width: i32, height: i32, format: u32, flags: Flags, ) -> ZwpLinuxBufferParamsV1

Create buffer.

DmabufHandler::created or DmabufHandler::failed will be invoked when the operation succeeds or fails.

pub fn create_immed<D>( self, width: i32, height: i32, format: u32, flags: Flags, qh: &QueueHandle<D>, ) -> (WlBuffer, ZwpLinuxBufferParamsV1)

where D: Dispatch<WlBuffer, DmaBufferData> + 'static,

Create buffer immediately.

On failure buffer is invalid, and server may raise protocol error or send DmabufHandler::failed.
