go-exp

A little GO library that provides additional functionality for generic maps and sets

Since the introduction of generics in GO, its experimental repository has a couple of packages that helps to write nicer code for slices and maps:

• https://pkg.go.dev/golang.org/x/exp/slices
• https://pkg.go.dev/golang.org/x/exp/maps

I felt like adding a bit more to it, therefore this add-on library was created.

Features

• github.com/adnsv/go-exp/maps package

  • flattening maps into slices of key-value pairs
  • sorting key-value pairs by key and by value
  • merging maps with conflict resolution
  • inverting maps with duplicate key detection
  • one-liner range for loops for key-ordered or value-ordered iterating over existing maps

• github.com/adnsv/go-exp/sets package

  • implements intersect, union, difference, and other set-like functionality for map[K comparable]struct{}
