Detailed Description

HTTP/3 server response-layer state after the 1-RTT handshake.

Field Documentation

qdyn

quic_qpack_dyn wired_h3srv_state::qdyn

RFC 9204 3.2 / 4.3.1: this connection's QPACK dynamic table, the peer's encoder stream instructions (Set Dynamic Table Capacity, Insert...) are applied to (see wired_h3srv_qpack_max_table).

Initialised empty (capacity 0) by wired_h3srv_state_init; a peer that never opens an encoder stream or never raises the capacity keeps it at 0, matching RFC 9204 3.2's "no dynamic table" default.

qpack_max_table_capacity

u64 wired_h3srv_state::qpack_max_table_capacity

RFC 9204 5 (SETTINGS_QPACK_MAX_TABLE_CAPACITY): the maximum dynamic table capacity (in bytes) this server has advertised to the peer – quic_qpack_capacity_within_limit's own limit argument when validating a received Set Dynamic Table Capacity instruction (9204-032).

0 (this SDK's current default: it never emits a non-zero value in its own SETTINGS) means the peer's encoder may not raise the table past 0 either.
