Implementations§

Source §

impl EnigmaMachine

Source

pub fn new() -> impl EnigmaBuilder

Creates a new Enigma machine with blank settings. The settings for the machine must be added using the methods of EnigmaBuilder; See the README for an example.

The returned value from this will always be Ok, and will be an Enigma machine with rotors 1, 1, 1, ring positions 1, 1, and 1, ring settings 1, 1, and 1, reflector A, and an empty plugboard.

Source

pub fn decode(&self, text: &str) -> String

Decodes the given text using this Enigma machine.

This is exactly the same as calling machine.encode(text), since the enigma cipher is symmetric; The only difference is semantic meaning and intent, i.e.,

assert_eq!(text, machine.decode(machine.decode(text)));
assert_eq!(text, machine.encode(machine.encode(text)));
assert_eq!(text, machine.decode(machine.encode(text)));
assert_eq!(text, machine.encode(machine.decode(text)));

§Parameters

text - The text to decode.

§Returns

The decoded text.

Source

pub fn encode(&self, text: &str) -> String

Encodes the given text using this Enigma machine.

This is exactly the same as calling machine.decode(text), since the enigma cipher is symmetric; The only difference is semantic meaning and intent, i.e.,

assert_eq!(text, machine.decode(machine.decode(text)));
assert_eq!(text, machine.encode(machine.encode(text)));
assert_eq!(text, machine.decode(machine.encode(text)));
assert_eq!(text, machine.encode(machine.decode(text)));
