Function decode 

pub fn decode(input: &str) -> Result<String, DecodeError>

Decode a Namecode string back to Unicode.

Returns Err(NotEncoded) if input doesn’t have the _N_ prefix.

Examples

use namecode::{decode, DecodeError};

assert_eq!(decode("_N_helloworld__fa0b").unwrap(), "hello world");
assert_eq!(decode("_N_foobar__da1d").unwrap(), "foo-bar");

// Strings without the _N_ prefix are not valid encodings
assert_eq!(decode("foo"), Err(DecodeError::NotEncoded));
