Struct teaclave_rpc::transport::Endpoint

pub struct Endpoint { /* private fields */ }

Channel builder.

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

Implementations

impl Endpoint

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

Convert an Endpoint from a static string.

Panics

This function panics if the argument is an invalid URI.

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

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

Convert an Endpoint from shared bytes.

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

pub fn user_agent<T>(self, user_agent: T) -> Result<Endpoint, Error>where
    T: TryInto<HeaderValue>,

Set a custom user-agent header.

user_agent will be prepended to Tonic’s default user-agent string (tonic/x.x.x). It must be a value that can be converted into a valid http::HeaderValue or building the endpoint will fail.

builder.user_agent("Greeter").expect("Greeter should be a valid header value");
// user-agent: "Greeter tonic/x.x.x"

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

Apply a timeout to each request.

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

Notes

This does not set the timeout metadata (grpc-timeout header) on the request, meaning the server will not be informed of this timeout, for that use Request::set_timeout.

pub fn connect_timeout(self, dur: Duration) -> Endpoint

Apply a timeout to connecting to the uri.

Defaults to no timeout.

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

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

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) -> Endpoint

Apply a concurrency limit to each request.

builder.concurrency_limit(256);

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

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>>) -> Endpoint

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>>
) -> Endpoint

Sets the max connection-level flow control for HTTP2

Default is 65,535

pub fn tls_config(self, tls_config: ClientTlsConfig) -> Result<Endpoint, Error>

Configures TLS for the endpoint.

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

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

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

Set http2 KEEP_ALIVE_INTERVAL. Uses hyper’s default otherwise.

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

Set http2 KEEP_ALIVE_TIMEOUT. Uses hyper’s default otherwise.

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

Set http2 KEEP_ALIVE_WHILE_IDLE. Uses hyper’s default otherwise.

pub fn http2_adaptive_window(self, enabled: bool) -> Endpoint

Sets whether to use an adaptive flow control. Uses hyper’s default otherwise.

pub async fn connect(&self) -> impl Future<Output = Result<Channel, Error>>

Create a channel from this config.

pub fn connect_lazy(&self) -> Channel

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
) -> impl Future<Output = Result<Channel, Error>>where
    C: 'static + MakeConnection<Uri> + Send,
    <C as MakeConnection<Uri>>::Connection: 'static + Unpin + Send,
    <C as MakeConnection<Uri>>::Future: 'static + Send,
    Box<dyn Error + Sync + Send + 'static, Global>: 'static + From<<C as MakeConnection<Uri>>::Error> + Send,

Connect with a custom connector.

This allows you to build a Channel that uses a non-HTTP transport. See the uds example for an example on how to use this function to build channel that uses a Unix socket transport.

The connect_timeout will still be applied.

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

Connect with a custom connector lazily.

This allows you to build a Channel that uses a non-HTTP transport connec to it lazily.

See the uds example for an example on how to use this function to build channel that uses a Unix socket transport.

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"));
