Available on crate features server and server-auto only.

Http2 part of builder.

Implementations

impl<E> Http2Builder<'_, E>

pub fn http1(&mut self) -> Http1Builder<'_, E>

Http1 configuration.

pub fn initial_stream_window_size( &mut self, sz: impl Into<Option<u32>>, ) -> &mut Self

Sets the SETTINGS_INITIAL_WINDOW_SIZE option for HTTP2 stream-level flow control.

Passing None will do nothing.

If not set, hyper will use a default.

pub fn initial_connection_window_size( &mut self, sz: impl Into<Option<u32>>, ) -> &mut Self

Sets the max connection-level flow control for HTTP2.

Passing None will do nothing.

If not set, hyper will use a default.

pub fn adaptive_window(&mut self, enabled: bool) -> &mut Self

Sets whether to use an adaptive flow control.

Enabling this will override the limits set in http2_initial_stream_window_size and http2_initial_connection_window_size.

pub fn max_frame_size(&mut self, sz: impl Into<Option<u32>>) -> &mut Self

Sets the maximum frame size to use for HTTP2.

Passing None will do nothing.

If not set, hyper will use a default.

pub fn max_concurrent_streams( &mut self, max: impl Into<Option<u32>>, ) -> &mut Self

Sets the SETTINGS_MAX_CONCURRENT_STREAMS option for HTTP2 connections.

Default is no limit (std::u32::MAX). Passing None will do nothing.

pub fn keep_alive_interval( &mut self, interval: impl Into<Option<Duration>>, ) -> &mut Self

Sets an interval for HTTP2 Ping frames should be sent to keep a connection alive.

Pass None to disable HTTP2 keep-alive.

Default is currently disabled.

Cargo Feature

pub fn keep_alive_timeout(&mut self, timeout: Duration) -> &mut Self

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

If the ping is not acknowledged within the timeout, the connection will be closed. Does nothing if http2_keep_alive_interval is disabled.

Default is 20 seconds.

Cargo Feature

pub fn max_send_buf_size(&mut self, max: usize) -> &mut Self

Set the maximum write buffer size for each HTTP/2 stream.

Default is currently ~400KB, but may change.

Panics

The value must be no larger than u32::MAX.

pub fn enable_connect_protocol(&mut self) -> &mut Self

Enables the extended CONNECT protocol.

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

Sets the max size of received header frames.

Default is currently ~16MB, but may change.

pub fn timer<M>(&mut self, timer: M) -> &mut Self

where M: Timer + Send + Sync + 'static,

Set the timer used in background tasks.

pub async fn serve_connection<I, S, B>( &self, io: I, service: S, ) -> Result<(), Box<dyn Error + Send + Sync>>

where S: Service<Request<Incoming>, Response = Response<B>>, S::Future: 'static, S::Error: Into<Box<dyn StdError + Send + Sync>>, B: Body + 'static, B::Error: Into<Box<dyn StdError + Send + Sync>>, I: Read + Write + Unpin + 'static, E: Http2ServerConnExec<S::Future, B>,

Bind a connection together with a Service.
