## Expand description

This library implements string similarity metrics.

## Enums

## Functions

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

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

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

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

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

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.

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

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