Module tonic::transport[−][src]

Expand description

Batteries included server and client.

This module provides a set of batteries included, fully featured and fast set of HTTP/2 server and client’s. These components each provide a or rustls tls backend when the respective feature flag is enabled, and provides builders to configure transport behavior.

Features

TLS support via rustls.
Load balancing
Timeouts
Concurrency Limits
Rate limiting

Examples

Client

let cert = std::fs::read_to_string("ca.pem")?;

let mut channel = Channel::from_static("https://example.com")
    .tls_config(ClientTlsConfig::new()
        .ca_certificate(Certificate::from_pem(&cert))
        .domain_name("example.com".to_string()))?
    .timeout(Duration::from_secs(5))
    .rate_limit(5, Duration::from_secs(1))
    .concurrency_limit(256)
    .connect()
    .await?;

channel.call(Request::new(BoxBody::empty())).await?;

Server

let cert = std::fs::read_to_string("server.pem")?;
let key = std::fs::read_to_string("server.key")?;

let addr = "[::1]:50051".parse()?;

Server::builder()
    .tls_config(ServerTlsConfig::new()
        .identity(Identity::from_pem(&cert, &key)))?
    .concurrency_limit_per_connection(256)
    .add_service(my_svc)
    .serve(addr)
    .await?;
