Struct EarlyFrameStreamContext 

pub struct EarlyFrameStreamContext { /* private fields */ }

Available on crate features http-backend and http and std only.

Implementations

impl EarlyFrameStreamContext

pub fn new_nop() -> EarlyFrameStreamContext

pub fn new_recorder() -> EarlyFrameStreamContext

pub fn new_replayer( frames: Vec<EarlyFrame>, ) -> (EarlyFrameStreamContext, Option<Settings>)

Replay frames, the client’s captured start of a connection.

A captured stream WINDOW_UPDATE follows the HEADERS of the first request, and browsers that send one raise every stream’s window that way. It is replayed as that policy: the same increment right after the HEADERS of each new stream, starting from the captured stream, rather than once for a stream ID the replaying client may never open.

pub fn first_stream_id(&self) -> Option<StreamId>

The stream a replayed connection opens first: the one its capture opened first, when the capture shows it.

pub fn stream_window_increment(&self) -> Option<u32>

The window increment a replaying client sends right after each new stream’s HEADERS.

impl EarlyFrameStreamContext

pub fn can_replay_next_frame(&self, next_stream_id: Option<StreamId>) -> bool

Returns whether the next replay frame can be consumed for the current stream state.

Callers that need codec capacity before consuming a replay frame can use this to avoid waiting on write readiness when there is no frame to replay. The actual replay still goes through Self::replay_next_frame.

pub fn next_frame_is_settings(&self) -> bool

Returns whether the next replay frame is a non-ACK SETTINGS frame.

pub fn has_replay_frame(&self) -> bool

Returns whether another captured frame remains to be replayed.

pub fn has_replayed_connection_window(&self) -> bool

Whether a connection WINDOW_UPDATE was consumed from this replay. Only meaningful while a replay still has pending frames.

pub fn record_priority_frame(&mut self, frame: &Priority)

pub fn record_settings_frame(&mut self, frame: &Settings)

pub fn record_windows_update_frame(&mut self, frame: WindowUpdate)

pub fn freeze_recorder(&mut self) -> Option<EarlyFrameCapture>

Does nothing in case the ctx is not a recorder.

pub fn replay_next_frame( &mut self, next_stream_id: Option<StreamId>, ) -> Option<EarlyFrame>
