Types ¶
type BitMap ¶
type BitMap[T constraints.Integer] []byte
BitMap 位图.
Example ¶
package main
import (
"fmt"
"github.com/xuender/oils/tags"
)
func main() {
tag := tags.NewBitMap(1, 2, 33)
fmt.Println(tag.Has(1))
fmt.Println(tag.Has(3))
fmt.Println(tag.Has(33))
fmt.Println(tag)
}
Output: true false true 1, 2, 33
func Intersection ¶
func Intersection[T constraints.Integer](elems ...BitMap[T]) BitMap[T]
Intersection 交集. nolint
type Tag ¶
type Tag uint64
Tag 标签.
标签内最多保存64个状态，数据库索引字段避免使用Tag，位运算无法使用索引加速.
Example ¶
package main
import (
"fmt"
"github.com/xuender/oils/tags"
)
func main() {
var tag tags.Tag
tag.Add(0, 1, 2)
fmt.Println(tag.Has(1))
fmt.Println(tag.Has(3))
tag.Add(3)
fmt.Println(tag.Len())
fmt.Println(tag.Slice())
tag.Del(2)
fmt.Println(tag.Len())
fmt.Println(tag.All(3, 4))
fmt.Println(tag.All(1, 3))
fmt.Println(tag.Any(4, 5))
fmt.Println(tag.Any(3, 4))
}
Output: true false 4 [0 1 2 3] 3 false true false true
