# Function base64::decode_config_buf [−] [src]

    pub fn decode_config_buf<T: AsRef<[u8]>>(
        input: T,
        config: Config,
        buffer: &mut Vec<u8>
    ) -> Result<(), DecodeError>

Decode from string reference as octets. Writes into the supplied buffer to avoid allocation. Returns a Result containing an empty tuple, aka ().

# Example

    extern crate base64;

    fn main() {
        let mut buffer = Vec::<u8>::new();
        base64::decode_config_buf("aGVsbG8gd29ybGR+Cg==", base64::STANDARD, &mut buffer).unwrap();
        println!("{:?}", buffer);

        buffer.clear();

        base64::decode_config_buf("aGVsbG8gaW50ZXJuZXR-Cg==", base64::URL_SAFE, &mut buffer)
            .unwrap();
        println!("{:?}", buffer);
    }
