Crate strsim[−][src]

This library implements string similarity metrics.

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.
