Expand description

The IPC route handler for https://fetch.spec.whatwg.org/#concept-request-transmit-body. This route runs in the script process, and will queue tasks to perform operations on the stream and transmit body chunks over IPC.

Implementations§

source§

impl TransmitBodyConnectHandler

source

pub fn new( stream: Trusted<ReadableStream>, task_source: NetworkingTaskSource, canceller: TaskCanceller, control_sender: IpcSender<BodyChunkRequest>, in_memory: Option<Vec<u8>>, source: BodySource, ) -> TransmitBodyConnectHandler

source

pub fn reset_in_memory_done(&mut self)

Reset in_memory_done, called when a stream is re-extracted from the source to support a re-direct.

source

fn re_extract(&mut self, chunk_request_receiver: IpcReceiver<BodyChunkRequest>)

Re-extract the source to support streaming it again for a re-direct. TODO: actually re-extract the source, instead of just cloning data, to support Blob.

source

fn transmit_source(&mut self)

In case of re-direct, and of a source available in memory, send it all in one chunk.

TODO: this method should be deprecated in favor of making re_extract actually re-extract a stream from the source. See #26686

source

fn start_reading(&mut self, sender: IpcSender<BodyChunkResponse>)

Take the IPC sender sent by net, so we can send body chunks with it. Also the entry point to https://fetch.spec.whatwg.org/#concept-request-transmit-body

source

fn stop_reading(&mut self, reason: StopReading)

Drop the IPC sender sent by net

source

fn transmit_body_chunk(&mut self)

Step 4 and following of https://fetch.spec.whatwg.org/#concept-request-transmit-body
