Crate stringedits

stringedits contains the Edit trait, which provides access to a number of iterators for small edits to strings. Based off the article How to Write A Spelling Corrector by Peter Norvig. Available under the MIT license.

Usage:

assert_eq!(vec!["!foo", "f!oo", "fo!o", "foo!"], "foo".inserts(&['!']).collect::<Vec<String>>());

Structs

CustomInsert

CustomReplaces

Iterator over all the words formed from the replacement of a character in a word with each letter in it’s custom alphabet see Edit::replaces

Deletions

Iterator over all the words formed from the delition of a single character from a word. See Edit::deletions

Dist1Edits

Iterator over all the distance-1 edits of a word; deletion, insertion, or replacement of one character, or transposition of two characters. See Edit::dist1edits

Dist2Edits

Iterator over all the distance-2 edits of a word. See Edit::dist2edits This stores a fairly large hashset & vector (of distance-1 edits) internally, so it’s not nearly as lightweight as the other iterator adaptors. I’d like to come up with a more elegant solution if I can, but I’d have to wrestle with lifetimes a lot.

Inserts

Iterator over all the words formed from the insertion of a letter in a…z in any position in a word, including before the first character and after the last see Edit::inserts

Replaces

Iterator over all the words formed from the replacement of a character in a word with a letter in a…z see Edit::replaces

Splits

Iterator over all the splits at a single position of a word. See Edit::splits

Transposes

Iterator over all transpositions of a single position of a word. See Edit::transposes

Constants

ASCII_LOWERCASE

The characters from ‘a’..=‘z’.

ASCII_UPPERCASE

The characters from ‘A’..=‘Z’.

Traits
