## Installation

FTPS support is disabled by default. To enable it `secure` should be activated in `Cargo.toml`.
```toml
[dependencies]
async_ftp = { version = "<version>", features = ["secure"] }
```

## Usage
```rust
use std::str;
use std::io::Cursor;
use async_ftp::FtpStream;

async fn async_main() -> Result<(), Box<dyn std::error::Error>> {
    // Create a connection to an FTP server and authenticate to it.
    let mut ftp_stream = FtpStream::connect("172.25.82.139:21").await?;
    let _ = ftp_stream.login("username", "password").await?;

    // Get the current directory that the client will be reading from and writing to.
    println!("Current directory: {}", ftp_stream.pwd().await?);
    
    // Change into a new directory, relative to the one we are currently in.
    let _ = ftp_stream.cwd("test_data").await?;

    // Retrieve (GET) a file from the FTP server in the current working directory.
    let remote_file = ftp_stream.simple_retr("ftpext-charter.txt").await?;
    println!("Read file with contents\n{}\n", str::from_utf8(&remote_file.into_inner()).await?);

    // Store (PUT) a file from the client to the current working directory of the server.
    let mut reader = Cursor::new("Hello from the Rust \"ftp\" crate!".as_bytes());
    let _ = ftp_stream.put("greeting.txt", &mut reader).await?;
    println!("Successfully wrote greeting.txt");

    // Terminate the connection to the server.
    let _ = ftp_stream.quit();
}

fn main() -> Result<(), Box<dyn std::error::Error>> {
    tokio::runtime::Builder::new()
        .threaded_scheduler()
        .enable_all()
        .build()
        .unwrap()
        .block_on(async_main())
}

```

## Development environment

All you need to develop rust-ftp and run the tests is Rust and Docker.
The `tests` folder contains a `Dockerfile` that installs and configures
the vsftpd server.

To create the Docker image:

```bash
docker build -t ftp-server tests
```

To start the FTP server that is tested against:

```bash
tests/ftp-server.sh
```

This script runs the `ftp-server` image in detached mode and starts the `vsftpd` daemon. It binds ports 21 (FTP) as well as the range 65000-65010 for passive connections.

Once you have an instance running, to run tests type:

```bash
cargo test
```

The following commands can be useful:
```bash
# List running containers of ftp-server image
# (to include stopped containers use -a option)
docker ps --filter ancestor=ftp-server

# To stop and remove a container
docker stop container_name
docker rm container_name

# To remove the image
docker rmi ftp-server
```
