Function base16::decode

pub fn decode<T: ?Sized + AsRef<[u8]>>(
    input: &T
) -> Result<Vec<u8>, DecodeError>

Decode bytes from base16, and return a new Vec<u8> containing the results.

Example

assert_eq!(&base16::decode("48656c6c6f20576f726c64".as_bytes()).unwrap(),
           b"Hello World");
assert_eq!(&base16::decode(b"deadBEEF").unwrap(),
           &[0xde, 0xad, 0xbe, 0xef]);
// Error cases:
assert_eq!(base16::decode(b"Not Hexadecimal!"),
           Err(base16::DecodeError::InvalidByte { byte: b'N', index: 0 }));
assert_eq!(base16::decode(b"a"),
           Err(base16::DecodeError::InvalidLength { length: 1 }));

Availability

This function is only available when the alloc feature is enabled, as it needs to produce a Vec.
