Struct tonic::transport::channel::Endpoint

pub struct Endpoint { /* fields omitted */ }

Channel builder.

This struct is used to build and configure HTTP/2 channels.

Implementations

impl Endpoint

pub fn from_static(s: &'static str) -> Self

Convert an Endpoint from a static string.

Endpoint::from_static("https://example.com");

pub fn from_shared(s: impl Into<Bytes>) -> Result<Self, InvalidUri>

Convert an Endpoint from shared bytes.

Endpoint::from_shared("https://example.com".to_string());

pub fn timeout(self, dur: Duration) -> Self

Apply a timeout to each request.

builder.timeout(Duration::from_secs(5));

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 concurrency_limit(self, limit: usize) -> Self

Apply a concurrency limit to each request.

builder.concurrency_limit(256);

pub fn rate_limit(self, limit: u64, duration: Duration) -> Self

Apply a rate limit to each request.

builder.rate_limit(32, Duration::from_secs(1));

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 tls_config(self, tls_config: ClientTlsConfig) -> Result<Self, Error>

Configures TLS for the endpoint.

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

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

pub fn http2_keep_alive_interval(self, interval: Duration) -> Self

Set http2 KEEP_ALIVE_INTERVAL. Uses hyper’s default otherwise.

pub fn keep_alive_timeout(self, duration: Duration) -> Self

Set http2 KEEP_ALIVE_TIMEOUT. Uses hyper’s default otherwise.

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

Set http2 KEEP_ALIVE_WHILE_IDLE. Uses hyper’s default otherwise.

pub async fn connect(&self) -> Result<Channel, Error>

Create a channel from this config.

pub fn connect_lazy(&self) -> Result<Channel, Error>

Create a channel from this config.

The channel returned by this method does not attempt to connect to the endpoint until first use.

pub async fn connect_with_connector<C>(
    &self,
    connector: C
) -> Result<Channel, Error> where
    C: MakeConnection<Uri> + Send + 'static,
    C::Connection: Unpin + Send + 'static,
    C::Future: Send + 'static,
    Box<dyn Error + Send + Sync>: From<C::Error> + Send + 'static, 

Connect with a custom connector.

pub fn uri(&self) -> &Uri

Get the endpoint uri.

let endpoint = Endpoint::from_static("https://example.com");

assert_eq!(endpoint.uri(), &Uri::from_static("https://example.com"));
