Options for tuning HTTP/2 connections.

Http2Options lets you adjust how HTTP/2 works—stream limits, window sizes, frame and header settings, and more. Most fields are optional and have sensible defaults. See each field for details.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

adaptive_window: bool

Whether to use adaptive flow control.

initial_stream_id: Option<u32>

The initial stream ID for the connection.

initial_conn_window_size: u32

The initial window size for HTTP/2 connection-level flow control.

initial_window_size: u32

The initial window size for HTTP/2 streams.

initial_max_send_streams: usize

The initial maximum number of locally initiated (send) streams.

max_frame_size: Option<u32>

The maximum frame size to use for HTTP/2.

keep_alive_interval: Option<Duration>

The interval for HTTP/2 keep-alive ping frames.

keep_alive_timeout: Duration

The timeout for receiving an acknowledgement of the keep-alive ping.

keep_alive_while_idle: bool

Whether HTTP/2 keep-alive should apply while the connection is idle.

max_concurrent_reset_streams: Option<usize>

The maximum number of concurrent locally reset streams.

max_send_buffer_size: usize

The maximum size of the send buffer for HTTP/2 streams.

max_concurrent_streams: Option<u32>

The maximum number of concurrent streams initiated by the remote peer.

max_header_list_size: Option<u32>

The maximum size of the header list.

max_pending_accept_reset_streams: Option<usize>

The maximum number of pending accept reset streams.

enable_push: Option<bool>

Whether to enable push promises.

header_table_size: Option<u32>

The header table size for HPACK compression.

enable_connect_protocol: Option<bool>

Whether to enable the CONNECT protocol.

no_rfc7540_priorities: Option<bool>

Whether to disable RFC 7540 Stream Priorities.

headers_pseudo_order: Option<PseudoOrder>

The HTTP/2 pseudo-header field order for outgoing HEADERS frames.

headers_stream_dependency: Option<StreamDependency>

The stream dependency for the outgoing HEADERS frame.

settings_order: Option<SettingsOrder>

The order of settings parameters in the initial SETTINGS frame.

priorities: Option<Priorities>

The list of PRIORITY frames to be sent after connection establishment.
