Function base64::decode_engine

pub fn decode_engine<E: Engine, T: AsRef<[u8]>>(
    input: T,
    engine: &E
) -> Result<Vec<u8>, DecodeError>

Decode from string reference as octets using the specified Engine. Returns a Result containing a Vec<u8>.

Example

    let bytes = base64::decode_engine(
        "aGVsbG8gd29ybGR+Cg==",
        &base64::engine::DEFAULT_ENGINE,
    ).unwrap();
    println!("{:?}", bytes);

    // custom engine setup
    let bytes_url = base64::decode_engine(
        "aGVsbG8gaW50ZXJuZXR-Cg",
        &base64::engine::fast_portable::FastPortable::from(
            &base64::alphabet::URL_SAFE,
            base64::engine::fast_portable::NO_PAD),

    ).unwrap();
    println!("{:?}", bytes_url);
