bitsets

Description

This small package provides bitset types for Go, leaning on math/bits under the hood. Example use cases might be marking certain indices of a small slice, or keeping a selection of values from an enumeration.

There are a few similar other packages out there, this particular one has the following feature set:

• Friendly to stack allocation, zero value is good to go
• Separate types for fixed-width versions of capacity 8, 16, 32, 64, 128 (bit8 through bit128), 1024 and 8192 (kbit and kbit8), plus a variable-width one (vbit)
• Fluent methods for usual logic operations (Not, And, Or, etc), each with a self-assigning version (AssignNot, AssignAnd, AssignOr, etc)
• Loop over the values (or contiguous sub-ranges) with range-func
• No dependencies

The various types provide a similar interface, so you can swap between with relative ease if needs change.
