I’m looking at the ‘countBits’ and ‘nthBitIndex’, there does not seem to be mutable versions of the same operations. I’m specifically trying to implement a succinct dictionary to improve the storage of a data structure I’m working on in the https://discourse.haskell.org/t/counting-words-but-can-we-go-faster/ project.
Ps. Always happy to talk to the author of the library
