Struct webrender_api::channel::Payload

pub struct Payload {
    pub epoch: Epoch,
    pub pipeline_id: PipelineId,
    pub display_list_data: Vec<u8>,
}

Fields

epoch: Epoch

An epoch used to get the proper payload for a pipeline id frame request.

TODO(emilio): Is this still relevant? We send the messages for the same pipeline in order, so we shouldn’t need it. Seems like this was only wallpapering (in most cases) the underlying problem in #991.

pipeline_id: PipelineId

A pipeline id to key the payload with, along with the epoch.

display_list_data: Vec<u8>

Implementations

impl Payload

pub fn construct_data( epoch: Epoch, pipeline_id: PipelineId, dl_data: &[u8], ) -> Vec<u8>

Convert the payload to a raw byte vector, in order for it to be efficiently shared via shmem, for example. This is a helper static method working on a slice.

pub fn to_data(&self) -> Vec<u8>

Convert the payload to a raw byte vector, in order for it to be efficiently shared via shmem, for example.

pub fn from_data(data: &[u8]) -> Payload

Deserializes the given payload from a raw byte vector.

Trait Implementations

impl Clone for Payload

fn clone(&self) -> Payload

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
