Trait WlPayload 

pub(crate) trait WlPayload: Send + 'static {
    // Required methods
    fn encode(
        &self,
        source: Option<&Dmabuf>,
        encoder: &mut FrameEncoder,
        width: i32,
        rgba: bool,
        frame_number: u64,
        qp: u32,
        force_idr: bool,
    ) -> Result<Vec<u8>, String>;
    fn rows(&self) -> Option<&[u8]>;
}

What a Wayland encode thread encodes a frame from: the packed rows a readback filled, or the GPU buffer a zero-copy session encodes in place.

Required Methods

fn encode( &self, source: Option<&Dmabuf>, encoder: &mut FrameEncoder, width: i32, rgba: bool, frame_number: u64, qp: u32, force_idr: bool, ) -> Result<Vec<u8>, String>

Encode the frame on a full-frame session. source stands in for the slot’s own buffer (WlFrame::source).

fn rows(&self) -> Option<&[u8]>

The rows, for the CPU path; None for a GPU buffer, which only a hardware session reads.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".

impl WlPayload for Dmabuf

fn encode( &self, source: Option<&Dmabuf>, encoder: &mut FrameEncoder, _width: i32, _rgba: bool, frame_number: u64, qp: u32, force_idr: bool, ) -> Result<Vec<u8>, String>

fn rows(&self) -> Option<&[u8]>

impl WlPayload for Vec<u8>

fn encode( &self, _source: Option<&Dmabuf>, encoder: &mut FrameEncoder, width: i32, rgba: bool, frame_number: u64, qp: u32, force_idr: bool, ) -> Result<Vec<u8>, String>

fn rows(&self) -> Option<&[u8]>
