Struct Http2Options 

pub struct Http2Options { /* private fields */ }

Available on crate feature h2 only.

HTTP/2 server configuration.

Build one with Http2Options::default and override individual fields with the builder methods, then hand it to Http2::new.

Unlike the framing/header limits below, the connection window settings (initial_stream_window_size and initial_connection_window_size) are advisory: a client may shrink them with its own SETTINGS, and the server honours the smaller value.

Implementations

impl Http2Options

pub fn handshake_timeout(self, handshake_timeout: Option<Duration>) -> Self

Sets the maximum time to wait for a client to send the HTTP/2 preface before aborting the connection.

pub fn send_continue_response(self, send_continue_response: bool) -> Self

Sends 100 Continue responses automatically when a request has a body.

Defaults to true.

pub fn send_date_header(self, send_date_header: bool) -> Self

Inserts a Date header into responses that lack one.

Defaults to true.

pub fn max_concurrent_streams(self, max_concurrent_streams: u32) -> Self

Sets the maximum number of concurrent streams allowed on a connection.

Defaults to 200.

pub fn initial_stream_window_size(self, initial_stream_window_size: u32) -> Self

Sets the initial per-stream flow-control window size advertised to the client. Defaults to 1_048_576.

pub fn initial_connection_window_size( self, initial_connection_window_size: u32, ) -> Self

Sets the initial connection-level flow-control window size. Defaults to 1_048_576.

pub fn max_frame_size(self, max_frame_size: u32) -> Self

Sets the maximum frame size the server will send or receive. Defaults to the RFC 9113 default (16_384); must not exceed 2^24 - 1.

pub fn max_header_list_size(self, max_header_list_size: u32) -> Self

Sets the maximum size of an uncompressed header list the server will accept. Defaults to 16_384.

pub fn enable_connect_protocol(self, enable: bool) -> Self

Sets whether to enable the Extended CONNECT protocol, allowing for example for tunneling WebSockets over HTTP/2. Defaults to false.

pub fn idle_timeout(self, idle_timeout: Option<Duration>) -> Self

Sets the idle timeout: a connection that receives no frame from the peer for this long is closed gracefully with a GOAWAY (RFC 9113 Section 10.5). Defaults to None (no idle timeout).
