# Features

`async-tls` can be used both in server and client programs. To save compilation times, you
can switch off parts of this for faster compile times.

To only use async-tls on a client, deactivate default features and use the "client" feature.

```toml
[dependencies.async-tls]
version = "0.8"
default-features = false
features = ["client"]
```

To only use async-tls on for the server side, deactivate default features and use the "server" feature.

```toml
[dependencies.async-tls]
version = "0.8"
default-features = false
features = ["server"]
```

### Simple Client

```rust
use async_tls::TlsConnector;
use async_std::net::TcpStream;

// ...

let tcp_stream = TcpStream::connect("rust-lang.org:443").await?;
let connector = TlsConnector::default();
let mut tls_stream = connector.connect("www.rust-lang.org", tcp_stream).await?;

// ...
```

### Client Example Program

See [examples/client](examples/client/src/main.rs). You can run it with:

```sh
cd examples/client
cargo run -- hsts.badssl.com
```

### Server Example Program

See [examples/server](examples/server/src/main.rs). You can run it with:

```sh
cd examples/server
cargo run -- 127.0.0.1:8080 --cert ../../tests/end.cert --key ../../tests/end.rsa
```

and point the client at it with:

```sh
cd examples/client
cargo run -- 127.0.0.1 --port 8080 --domain localhost --cafile ../../tests/end.chain
```

**NOTE**: Don't ever use those certificate files anywhere but for testing!
