Available on crate feature h2 only.

Per-connection behavior options.

Fields

send_continue_response: bool

Answer requests with 100 Continue when they carry expect: 100-continue.

send_date_header: bool

Add a Date header to responses.

max_concurrent_streams: u32

SETTINGS_MAX_CONCURRENT_STREAMS announced to the peer.

initial_stream_window_size: u32

SETTINGS_INITIAL_WINDOW_SIZE: per-stream DATA credit we start with.

initial_connection_window_size: u32

Connection-level DATA credit we start with (RFC 9113 Section 6.9.1).

max_frame_size: u32

Largest frame (payload) we send or receive (SETTINGS_MAX_FRAME_SIZE).

max_header_list_size: u32

Largest decoded header list we accept (SETTINGS_MAX_HEADER_LIST_SIZE).

enable_connect_protocol: bool

Whether to enable Extended CONNECT

idle_timeout: Option<Duration>

Close the connection after this long with no frame from the peer (RFC 9113 Section 10.5). None disables the idle timeout.

max_local_error_reset_streams: Option<usize>

Maximum number of RST_STREAM frames we send in response to protocol errors made by the peer over the connection’s lifetime. None disables the limit; when it is exceeded the connection closes with GOAWAY ENHANCE_YOUR_CALM (RFC 9113 Section 10.5.2).

max_pending_accept_reset_streams: Option<usize>

Maximum number of streams the peer reset before we accepted them. None disables the limit; when it is exceeded the connection closes with GOAWAY ENHANCE_YOUR_CALM (RFC 9113 Section 10.5.2).

max_continuation_frames: usize

Maximum number of frames that may compose a single, not-yet-finalized header field block (HEADERS/CONTINUATION). Beyond this a stream is reset as a CONTINUATION flood (CVE-2024-27919).
