Implementations

impl Config

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

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

Default is 65,535

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

Sets the max connection-level flow control for HTTP2

Default is 65,535

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

Sets the SETTINGS_MAX_CONCURRENT_STREAMS option for HTTP2 connections.

Default is no limit (None).

pub fn max_connection_age(self, max_connection_age: Duration) -> Self

Sets the maximum time option in milliseconds that a connection may exist

Default is no limit (None).

pub fn http2_keepalive_interval( self, http2_keepalive_interval: Option<Duration>, ) -> Self

Set whether HTTP2 Ping frames are enabled on accepted connections.

If None is specified, HTTP2 keepalive is disabled, otherwise the duration specified will be the time interval between HTTP2 Ping frames. The timeout for receiving an acknowledgement of the keepalive ping can be set with Config::http2_keepalive_timeout.

Default is no HTTP2 keepalive (None)

pub fn http2_keepalive_timeout( self, http2_keepalive_timeout: Option<Duration>, ) -> Self

Sets a timeout for receiving an acknowledgement of the keepalive 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.

pub fn http2_adaptive_window(self, enabled: Option<bool>) -> Self

Sets whether to use an adaptive flow control. Defaults to false. Enabling this will override the limits set in http2_initial_stream_window_size and http2_initial_connection_window_size.

pub fn http2_max_pending_accept_reset_streams(self, max: Option<usize>) -> Self

Configures the maximum number of pending reset streams allowed before a GOAWAY will be sent.

This will default to whatever the default in h2 is. As of v0.3.17, it is 20.

See https://github.com/hyperium/hyper/issues/2877 for more information.

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

Set whether TCP keepalive messages are enabled on accepted connections.

If None is specified, keepalive is disabled, otherwise the duration specified will be the time to remain idle before sending TCP keepalive probes.

Default is no keepalive (None)

pub fn tcp_nodelay(self, enabled: bool) -> Self

Set the value of TCP_NODELAY option for accepted connections. Enabled by default.

pub fn http2_max_header_list_size(self, max: impl Into<Option<u32>>) -> Self

Sets the max size of received header frames.

This will default to whatever the default in hyper is. As of v1.4.1, it is 16 KiB.

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

Sets the maximum frame size to use for HTTP2.

Passing None will do nothing.

If not set, will default from underlying transport.

pub fn accept_http1(self, accept_http1: bool) -> Self

Allow this accepting http1 requests.

Default is true.

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

Allow accepting insecure connections when a tls_config is provided.

This will allow clients to connect both using TLS as well as without TLS on the same network interface.

Default is false.

NOTE: This presently will only work for tokio::net::TcpStream IO connections
