# Crate strsim[−][src]

This library implements string similarity metrics.

## Functions

damerau_levenshtein |
Like optimal string alignment, but substrings can be edited an unlimited number of times, and the triangle inequality holds. |

hamming |
Calculates the number of positions in the two strings where the characters differ. Returns an error if the strings have different lengths. |

jaro |
Calculates the Jaro similarity between two strings. The returned value is between 0.0 and 1.0 (higher value means more similar). |

jaro_winkler |
Like Jaro but gives a boost to strings that have a common prefix. |

levenshtein |
Calculates the minimum number of insertions, deletions, and substitutions required to change one string into the other. |

normalized_damerau_levenshtein |
Calculates a normalized score of the Damerau–Levenshtein algorithm between 0.0 and 1.0 (inclusive), where 1.0 means the strings are the same. |

normalized_levenshtein |
Calculates a normalized score of the Levenshtein algorithm between 0.0 and 1.0 (inclusive), where 1.0 means the strings are the same. |

osa_distance |
Like Levenshtein but allows for adjacent transpositions. Each substring can only be edited once. |
