Package slice
do something for a slice.
Usage
package main
import (
"log"
"strconv"
"strings"
"github.com/QisFj/godry/slice"
)
func main() {
is := []int{1, 2, 3, 4, 5, 6}
ss := slice.Map(is, func(i int, v int) string {
return strconv.Itoa(v)
})
log.Printf("after map: %#v\n", ss)
ss = slice.Filter(ss, func(_ int, v string) bool {
return strings.ContainsAny(v, "135")
})
log.Printf("after filter: %#v\n", ss)
}
Map
Map a slice to another slice.
Filter
Filter some elements of slice.

Functions ¶
func ToMap ¶
func ToMap[I any, K comparable, V any](slice []I, kf func(I) K, vf func(I) V) map[K]V
ToMap convert a slice to a map if vf is nil, will try to use elem of slice as value
func ToMapItself ¶ added in v0.2.0
func ToMapItself[I any, K comparable](slice []I, kf func(I) K) map[K]I
ToMapItself convert a slice to a map like ToMap, but the value of map is the elem of slice itself
Types ¶
type KV ¶
type KV[K comparable, V any] struct { Key K Value V }
func KVsOfMap ¶
func KVsOfMap[K comparable, V any](m map[K]V) []KV[K, V]
KVsOfMap return a kv slice from map
