Functions

func Add

func Add[E constraints.Integer](tag E, elems ...E) E

Add 增加.

Example

ExampleAdd 增加例子.

package main

import (
	"fmt"

	"github.com/xuender/kit/tags"
)

func main() {
	tag := tags.Add(1<<3, 1<<4)

	fmt.Println(tag)

}

Output:

24

func Del

func Del[E constraints.Integer](tag E, elems ...E) E

Del 删除.

Example

ExampleDel 删除例子.

package main

import (
	"fmt"

	"github.com/xuender/kit/tags"
)

func main() {
	tag := tags.Add(1<<3, 1<<4)
	tag = tags.Del(tag, 1<<3, 1<<5)

	fmt.Println(tag)

}

Output:

16

func Has

func Has[E constraints.Integer](tag E, elems ...E) bool

Has 包含任何一个标签.

Example

ExampleHas 包含例子.

package main

import (
	"fmt"

	"github.com/xuender/kit/tags"
)

func main() {
	tag := tags.Add(1<<3, 1<<4)
	query1 := tags.Add(1 << 3)
	query2 := tags.Add(1<<3, 1<<4)
	query3 := tags.Add(1 << 2)

	fmt.Println(tags.Has(tag, query1))
	fmt.Println(tags.Has(tag, query1, query2))
	fmt.Println(tags.Has(tag, query3))
	fmt.Println(tags.Has(tag, query3, query2))

}

Output:

true
true
false
true

func Hit

func Hit[E constraints.Integer](tag E, elems ...E) bool

Hit 命中所有标签.

Example

ExampleHit 命中例子.

package main

import (
	"fmt"

	"github.com/xuender/kit/tags"
)

func main() {
	tag := tags.Add(1<<3, 1<<4)
	query1 := tags.Add(1 << 3)
	query2 := tags.Add(1<<3, 1<<4)
	query3 := tags.Add(1 << 2)

	fmt.Println(tags.Hit(tag, query1))
	fmt.Println(tags.Hit(tag, query1, query2))
	fmt.Println(tags.Hit(tag, query3))
	fmt.Println(tags.Hit(tag, query3, query2))

}

Output:

true
true
false
false
