# Introduction
This is a Base64 encoding library as described in [RFC4648](https://www.rfc-editor.org/rfc/rfc4648).
This library encodes and decodes random data into ASCII characters using an appropriate
Base64 library. It is designed to leverage the abstractions in Rust's std library
in order to be generic over io streams. That is to say, you can read from anything
implementing **Read** and write the encoded or decoded output to anything which
implements **Write**.

# Usage
Add the crate to your `Cargo.toml` file.
```Toml
# Cargo.toml
[dependencies]
b64 = { git = "https://git.hitchhiker-linux.org/jeang3nie/b64_rs.git" }
```
## Encoding
Encoding 'Hello, World!' into a new `String`, wrapping at 76 characters and using
the default alphabet.
```
use {
    std::io::Read,
    b64::Encoder,
};

fn main() {
    let mut encoder = Encoder::new("Hello, World!".as_bytes(), vec![], None, Some(76));
    encoder.encode().unwrap();
    assert_eq!(encoder.output(), b"SGVsbG8sIFdvcmxkIQ==\n");
}
```

## Decoding
```
use {
    std::io::Read,
    b64::Decoder,
};

fn main() {
    let mut decoder = Decoder::new("SGVsbG8sIFdvcmxkIQ==".as_bytes(), vec![], None, false);
    assert_eq!(decoder.decode().unwrap(), b"Hello, World!");
}
```
