Data Fields
int	in_use
	0 = free slot
u64	stream_id
	the WT uni stream id this slot reassembles
usz	type_len
	bytes the leading type varint occupied on the wire (RFC 9000 16: 2 for 0x54's own encoding, but recorded rather than assumed), same role as wired_srvloop_wt_stream_slot's sig_len.
wired_srvloop_wt_window	win
	receive-window bookkeeping, see its doc
u8	buf [WIRED_SRVLOOP_WT_BUF_CAP]
	offset-indexed bytes past the type varint, relative to win.base.
u8	fin
	1 once this stream's FIN was seen
u64	fin_off
	the absolute offset FIN was seen at; valid only when fin
int	offered
	1 once wired_wt_session_offer_stream has been called for this slot's stream_id, mirroring wired_srvloop_wt_stream_slot's offered field.
int	wt_session_slot
	The session slot index this stream was offered to, mirroring wired_srvloop_wt_stream_slot's wt_session_slot field (see its doc).
u64	delivered_len
	how much of the stream (absolute offset) has already been delivered to an app-facing stream-data callback, mirroring wired_srvloop_wt_stream_ slot's delivered_len field (see its doc for the ownership split).
int	fin_delivered
	1 once a fin=1 delivery has been made, mirroring wired_srvloop_wt_stream_slot's fin_delivered field.
u64	credit_advertised
	MAX_STREAM_DATA last advertised for this stream, mirroring wired_srvloop_wt_stream_slot's credit_advertised field.

Detailed Description

One WebTransport uni stream's cross-datagram reassembly state (draft-ietf- webtrans-http3-15 4.3).

free (in_use == 0) until the stream's leading type-id varint (0x54, RFC 9000 2.1 uni stream) is first sighted. buf holds the stream's bytes AFTER the type varint — mirrors wired_srvloop_wt_stream_ slot's buf/sig_len shape (renamed type_len here since a uni stream's offset-0 varint is a stream TYPE, not a mid-stream signal).

Field Documentation

buf

u8 wired_srvloop_wt_uni_stream_slot::buf[WIRED_SRVLOOP_WT_BUF_CAP]

offset-indexed bytes past the type varint, relative to win.base.

ponytail: a write outside the granted window is dropped, same policy as wired_srvloop_wt_stream_slot's buf.
