tcp-stream 0.34.10

Runtime

• tokio (default)
• smol
• async-global-executor

TLS backends

• native-tls
• openssl
• rustls (default)

Rustls certificates store

• rustls-platform-verifier (default)
• rustls-native-certs
• rustls-webpki-roots-certs

Warning about crypto backends for rustls

A crypto implementation must be enabled in rustls using feature flags. We mimic what rustls does, providing one feature flag per implementation and enabling the same as rustls by default. Available options are:

• rustls--aws_lc_rs (default)
• rustls--ring

Example

To connect to a remote server:

use tcp_stream::{HandshakeError, TcpStream, TLSConfig};

use std::io::{self, Read, Write};

fn main() {
    let stream = TcpStream::connect("google.com:443").unwrap();
    let mut stream = stream.into_tls("google.com", TLSConfig::default());

    while let Err(HandshakeError::WouldBlock(mid_handshake)) = stream {
        stream = mid_handshake.handshake();
    }

    let mut stream = stream.unwrap();

    while let Err(err) = stream.write_all(b"GET / HTTP/1.0\r\n\r\n") {
        if err.kind() != io::ErrorKind::WouldBlock {
            panic!("error: {:?}", err);
        }
    }
    stream.flush().unwrap();
    let mut res = vec![];
    while let Err(err) = stream.read_to_end(&mut res) {
        if err.kind() != io::ErrorKind::WouldBlock {
            panic!("stream error: {:?}", err);
        }
    }
    println!("{}", String::from_utf8_lossy(&res));
}
