Release Notes

trillium-rs/trillium (trillium)

v1.3.0

Compare Source

Added

• Listener — available in Conn state on every server-common based server.
• Listeners
• Info::listeners() -> &[Listener] — every listener the server is bound to. Populated by server-common-based servers during startup

v1.2.0

Compare Source

Added

• Upgrade::send_trailers(self, &Headers) -> io::Result<()>
• Upgrade::request_trailers() -> Option<&Headers>

v1.1.0

Added

• Transport::negotiated_alpn() -> Option<Cow<'_, [u8]>> — optional trait method (defaults to None); runtime adapters use the result to dispatch between HTTP/1.1 and HTTP/2 on the same TLS listener
• trillium::Upgrade now implements AsRef<trillium_http::Upgrade<Box<dyn Transport>>> and AsMut<...>, exposing the full underlying fieldwork accessor surface to downstream callers (e.g. trillium-webtransport) without Upgrade having to enumerate every accessor up front.
