Available on crate features http and std only.

Per-conn override for the h2 server’s initial SETTINGS frame, set on the IO’s Extensions. Any field left None retains the builder default. Some(value) overrides one-to-one; this type can’t express “explicitly unset” — set the builder directly if you need that.

Used by arbitrary connection layers, including MITM relays. A complete initial_settings frame takes precedence over scalar SETTINGS overrides; connection-window and adaptive-flow options remain independent.

Fields

initial_settings: Option<Arc<Settings>>

Replace the complete initial SETTINGS frame, including order and omissions. Semantic codec/stream limits use this same frame; a stream or header-list cap it omits keeps the builder’s value, enforced unadvertised. Absent keeps builder defaults. A server frame must not contain SETTINGS_ENABLE_PUSH.

enable_connect_protocol: Option<bool>

Whether to advertise the extended CONNECT protocol in the initial SETTINGS frame.

max_concurrent_streams: Option<u32>

SETTINGS_MAX_CONCURRENT_STREAMS.

header_table_size: Option<u32>

SETTINGS_HEADER_TABLE_SIZE.

max_frame_size: Option<u32>

SETTINGS_MAX_FRAME_SIZE.

max_header_list_size: Option<u32>

SETTINGS_MAX_HEADER_LIST_SIZE.

initial_stream_window_size: Option<u32>

SETTINGS_INITIAL_WINDOW_SIZE (stream-level flow control).

initial_connection_window_size: Option<u32>

Connection-level flow-control window.

adaptive_window: Option<bool>

Whether to use adaptive flow control. If Some(true), the stream/connection window-size overrides above are reset to the spec default before adaptive control takes over.
