# async-proxy: fast proxy clients implementation
Async proxy is a fast and flexible, as well as asyncronous implementation of proxy clients in the Rust programming language




## Getting started
Add the line below in your `Cargo.toml` file
```
async-proxy = "0.2.5"
```
## Protocols
The library supports these protocols
* SOCKS4 (Stable)
* SOCKS5 (Without auth, stable)
* HTTP(s) (Working on, WIP)
## Example
An example of using an async-proxy `Socks4` protocol implementation without `ident` in connection needed
```rust
use async_proxy::clients::socks4::no_ident::Socks4NoIdent;
use async_proxy::general::ConnectionTimeouts;
use async_proxy::proxy::ProxyConstructor;
use tokio::net::TcpStream;
use std::net::{SocketAddr, SocketAddrV4};
use std::time::Duration;
use std::process::exit;
#[tokio::main]
async fn main() {
// The address of the proxy server that
// will be used to connect through.
// (We used a random proxy from `https://hidemy.name/en/proxy-list/`)
let proxy_addr: SocketAddr = "104.248.63.15:30588".parse().unwrap();
// The address of the destination service
// that we will be connecting to through proxy.
// (We used a tcp echo server from `http://tcpbin.org/`)
let dest_addr: SocketAddrV4 = "52.20.16.20:30000".parse().unwrap();
// Setting up timeouts
let timeouts = ConnectionTimeouts::new(
// Connecting timeout
Duration::from_secs(8),
// Write timeout
Duration::from_secs(8),
// Read timeout
Duration::from_secs(8)
);
// Creating the socks4 constructor,
// using which we will establish a connection
// through proxy
let socks4_proxy = Socks4NoIdent::new(dest_addr, timeouts);
// Connecting to the stream and getting the readable and
// writable stream, or terminating the script if it is
// unable to connect
let stream = TcpStream::connect(proxy_addr)
.await
.expect("Unable to connect to the proxy server");
// Connecting to the service through proxy
let stream = match socks4_proxy.connect(stream).await {
Ok(stream) => {
// Successfully connected to the service
stream
},
Err(e) => {
// -- handling the error -- //
exit(1);
}
};
}
```
