Struct ranagrams::util::Translator

pub struct Translator {
    pub normalizer: fn(_: &str) -> String,
    // some fields omitted
}

A Translator converts between alphabetic and numeric representations of words. For anagram calculation words are treated as pure numeric sequences. The translator converts back and forth and also keeps track of character frequences in order to produce a dense trie representation of a word list.

Fields

normalizer: fn(_: &str) -> String

Implementations

impl Translator

pub fn new<'a, I: Iterator<Item = &'a str>>(
    normalizer: fn(_: &str) -> String,
    i: I
) -> Translator

pub fn alphabet_size(&self) -> usize

pub fn count(&self, word: &str) -> Option<CharCount>

pub fn snrt(&self, i: &usize) -> Option<&char>

pub fn etalsnart(&self, ints: &[usize]) -> Option<String>

pub fn translate(&self, word: &str) -> Option<Vec<usize>>

pub fn unfamiliar_character(&self, word: &str) -> (String, String)

for construction of an error message when translate fails

Trait Implementations

impl Clone for Translator

pub fn clone(&self) -> Translator

Returns a copy of the value.

pub fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
