stringset

Implementation of a Set of strings in Go. Supports all the standard set operations.

Package stringset provides the capabilities of a standard set with strings, including the standard set operations (add, delete, check membership, intersection, union) and a specialized ability to have a "negative" set for intersections.

Negative sets are useful for inverting the sense of a set when combining them using Intersection. Negative sets do not change the behavior of any other set operations, including Union and Difference. Negative operations were created for managing a set of tags, where it is useful to be able to search for items that contain some tags but do not contain others.

The API is designed to be chainable so that common operations become one-liners, and it is designed to be easy to use with slices of strings.

This package does not return errors. Set operations should be fast and chainable; adding items more than once, or attempting to remove things that don't exist are not errors.
