Provides the alphabet!() macro. It can be used to create const alphabets easily.
Usually you would have to write alphabets in a cumbersome way:
const HEX: [char; 16] = ['0', '1', '2', '3',
'4', '5', '6', '7',
'8', '9', 'a', 'b',
'c', 'd', 'e', 'f'];
assert_eq!(HEX.len(), 16);
assert_eq!(HEX[5], '5');
assert_eq!(HEX[10], 'a');
But with the alphabet!() macro this can be done way easier.
use alphabet_macro::alphabet;
alphabet!(HEX = "0123456789abcdef");
assert_eq!(HEX.len(), 16);
assert_eq!(HEX[5], '5');
assert_eq!(HEX[10], 'a');
The alphabet!() macro expands to the snippet above, while being easier to read, write and understand.
