Is there a kotlin stdlib cross-platform implementation of BitSet? That is, something that lets me do common bit maniuplations but without a fixed size?

The java.util.BitSet has all sorts of ugly java (read: old) conventions around cloning, blyeh, i dont like it.

[hho]

BitSet is currently native only and therefore has been marked "obsolete" with Kotlin 1.9.0 – according to the release notes you can keep using obsolete classes, but they'll be replaced in a later release. 🤷‍♂️

it has the same gross mutable methods as java does!

eeeew.

clearly BitSet.andNot(r: BitSet): BitSet is the correct signature

@groostav If you have ideas how an ideal BitSet type could be designed, please drop them here: https://youtrack.jetbrains.com/issue/KT-55163/BitSet-for-Kotlin-multiplatform-projects

I know this is a tad late, however I'm gonna post it anyways

korlibs has a class called BitSet, however it does not contain methods to allow you to perform binary operations on the bitset, only set and get. However, if you wish to add those, you could always PR it to them.

do note: the documentation for the korlibs libraries are rather lacking.
