Functions

func Lookup

func Lookup[T any](vs []T, index int) (T, bool)

Example

package main

import (
	"go.llib.dev/testcase/internal/slicekit"
)

func main() {
	vs := []int{2, 4, 8, 16}
	slicekit.Lookup(vs, 0)      // -> return 2, true
	slicekit.Lookup(vs, 0-1)    // lookup previous -> return 0, false
	slicekit.Lookup(vs, 0+1)    // lookup next -> return 4, true
	slicekit.Lookup(vs, 0+1000) // lookup 1000th element -> return 0, false
}

func Merge

func Merge[T any](slices ...[]T) []T

Merge will merge every []T slice into a single one.

Example

package main

import (
	"go.llib.dev/testcase/internal/slicekit"
)

func main() {
	var (
		a   = []string{"a", "b", "c"}
		b   = []string{"1", "2", "3"}
		c   = []string{"1", "B", "3"}
		out = slicekit.Merge(a, b, c)
	)
	_ = out // []string{"a", "b", "c", "1", "2", "3", "1", "B", "3"}
}

func ReverseLookup

func ReverseLookup[T any](vs []T, index int) (T, bool)
