mapset
import "github.com/zyedidia/generic/mapset"
Package mapset provides an implementation of a set using the built-in map.
Example
package main
import (
"fmt"
"github.com/zyedidia/generic/mapset"
)
func main() {
set := mapset.New[string]()
set.Put("foo")
set.Put("bar")
set.Put("baz")
fmt.Println("foo", set.Has("foo"))
fmt.Println("quux", set.Has("quux"))
set.Remove("foo")
fmt.Println("foo", set.Has("foo"))
fmt.Println("bar", set.Has("bar"))
set.Clear()
fmt.Println("foo", set.Has("foo"))
fmt.Println("bar", set.Has("bar"))
}
Output
foo true
quux false
foo false
bar true
foo false
bar false

type Set
Set implements a hashset, using the hashmap as the underlying storage.
type Set[K comparable] struct {
// contains filtered or unexported fields
}
func New
func New[K comparable]() Set[K]
New returns an empty hashset.
func Of
func Of[K comparable](vals ...K) Set[K]
Of returns a new hashset initialized with the given 'vals'
func (Set[K]) Clear
func (s Set[K]) Clear()
Clear removes all elements from the set.
func (Set[K]) Each
func (s Set[K]) Each(fn func(key K))
Each calls 'fn' on every item in the set in no particular order.
func (Set[K]) Has
func (s Set[K]) Has(val K) bool
Has returns true only if 'val' is in the set.
func (Set[K]) Put
func (s Set[K]) Put(val K)
Put adds 'val' to the set.
func (Set[K]) Remove
func (s Set[K]) Remove(val K)
Remove removes 'val' from the set.
func (Set[K]) Size
func (s Set[K]) Size() int
Size returns the number of elements in the set.
