Struct wordfeud_solver::Codec

pub struct Codec { /* fields omitted */ }

Translate from string to label codes and vice versa. Each wordfeud tile is translated to a code.

• 0: No tile (empty square)
• 1 .. 26: a .. z
• 27 .. 31: Non-ascii tiles, depending on codec
• 64: Blank tile * (unassigned)
• 65 .. 90: A .. Z (blank tile assigned to a..z)
• 91 .. 95: Blank tile assigned, depending on codec

Implementations

impl Codec

pub fn new(extend: &[&str]) -> Codec

Return a new Codec for "a".."z", "*", " ", extended with the non-ascii tiles from extend.

Examples

use wordfeud_solver::Codec;
let codec = Codec::new(&["ä", "ö", "ü"]);

pub fn encode(&self, word: &str) -> Result<Vec<u8>, Error>

Encode string, and return a list of u8 labels.

Errors

An error is returned if the string can not be encoded with the codec.

Examples

use wordfeud_solver::{Codec, Error};
let codec = Codec::new(&["ä", "ö", "ü"]);
let labels = codec.encode("azAZä *")?;
assert_eq!(labels, vec![1,26,65,90,27,0,64]);

pub fn decode(&self, codes: &[Code]) -> Vec<String>

Decode labels, and return a list of strings.

Errors

An error is returned if the labels can not be decoded with the codec.

Examples

use wordfeud_solver::{Codec, Error};
let codec = Codec::new(&["ä", "ö", "ü"]);
let labels = &[1,26,65,90,27,0,64];
let decoded = codec.decode(labels);
assert_eq!(decoded, &["a","z","A","Z","ä",".", "*"]);
