Struct StreamState 

struct StreamState<'a> {
    stream_id: u64,
    key: StreamKey,
    is_control_stream: bool,
    pending: &'a mut PendingQueue,
    deferred: &'a mut DeferredEffects,
}

The deferred-write state of one stream direction, plus the two facts every teardown helper needs about it.

Bundled because PendingQueue and DeferredEffects are only correct when they move together, and because propagate_reset needs both the stream’s identity and its queue.

Fields

stream_id: u64

key: StreamKey

This stream’s session-local identity, minted once at accept and carried to every site it reaches. Distinct from stream_id, which is the transport id and is 0 on every WebTransport stream.

is_control_stream: bool

true selects the control-stream rules at Site::StreamEnd, where a synthesized reset is a session-level protocol violation and is refused rather than executed.

pending: &'a mut PendingQueue

deferred: &'a mut DeferredEffects
