Function to measure similarity between strings?

Help
1

I think I saw a function somewhere in the stdlib that measures the similarity between strings but I fail to find it now. Id be glad if someone either tells me its not there or tells me how its called.

Not sure about in std, but these might help levenshtein distance implementation in zig · GitHub GitHub - nektro/zig-leven: Measure the difference between two slices using the Levenshtein distance algorithm
