MappedBits builds a Bits map from a set of values (e.g.

SetToSlice returns a slice containing the keys of the provided Set/map.

SliceToSet returns a Set/map whose keys are formed by the values in the slice argument.

WithTransform will apply the provided transformer function to the passed key values in the MappedBits constructor function.

Bits wraps an unsigned integer that can be used as a bit map.

BuilderOpt allows defining option for building Bits map in the MappedBits method.

Map2 implements a 2-level map where each 1st-level key maps to a 2nd level map.

MultiCounter maps a counter to a given key.
