Module tonic::transport

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 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(tonic::body::empty_body())).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?;
