Collections for Golang using generics. Currently containing Hash Set.

Implementation of missing colections for Golang using Generics.
Free of dependencies.
Curently in early development phase.

Requirements

Go 1.18+

Install

$ go get -u github.com/ferreiravinicius/gollections

Set

Set is a collection that contains no duplicate elements.
All implementations follows the set.Set interface.

Hash Set

Implemention of set backed by a hash table (Go builtin Map).
Order of insertion is not guaranteed.
This implementation is not synchronized.

API

Importing

import "github.com/ferreiravinicius/goset/hashset"

Create a new empty set

set := hashset.New[int]() 

Create a new set initialized

set := hashset.From(1, 2, 3) 

items := []int{4, 5, 6}
set := hashset.From(items...) 

Create a new set with initial capacity

set := hashset.WithCapacity[int](100) 

Iterating over the set using builtin loop

set := hashset.From(1, 2, 3)
for item := range set {
  // foo(item)
}

Iterating over the set using ForEach

set := hashset.From(1, 2, 3) 
set.ForEach(func(item int) { 
 // foo(item) 
})
