> [Native TLS](https://crates.io/crates/native-tls) for [async-std](https://crates.io/crates/async-std) or [tokio](https://crates.io/crates/tokio).

This crate uses SChannel on Windows (via [schannel](https://crates.io/crates/schannel)), Secure Transport on 
OSX (via [security-framework](https://crates.io/crates/security-framework)), and OpenSSL (via [openssl](https://crates.io/crates/openssl)) on 
all other platforms.

## Installation

```sh
$ cargo add async-native-tls
```

#### Cargo Feature Flags

 * `runtime-async-std` (on by default): Use the `async-std` runtime.

 * `runtime-tokio`: Use the `tokio` runtime. This is mutually exclusive with `runtime-async-std`.

## Example

#### async-std

> Requires `runtime-async-std` feature (on by default).

```toml
# Cargo.toml
[dependencies]
async-native-tls = "0.4"
```

```rust
use async_std::prelude::*;
use async_std::net::TcpStream;

let stream = TcpStream::connect("google.com:443").await?;
let mut stream = async_native_tls::connect("google.com", stream).await?;
stream.write_all(b"GET / HTTP/1.0\r\n\r\n").await?;

let mut res = Vec::new();
stream.read_to_end(&mut res).await?;
println!("{}", String::from_utf8_lossy(&res));
```

#### tokio

> Requires `runtime-tokio` feature.

```toml
# Cargo.toml
[dependencies]
async-native-tls = { version = "0.4", default-features = false, features = [ "runtime-tokio" ] }
```

```rust
use tokio::prelude::*;
use tokio::net::TcpStream;

let stream = TcpStream::connect("google.com:443").await?;
let mut stream = async_native_tls::connect("google.com", stream).await?;
stream.write_all(b"GET / HTTP/1.0\r\n\r\n").await?;

let mut res = Vec::new();
stream.read_to_end(&mut res).await?;
println!("{}", String::from_utf8_lossy(&res));
```
