slices2

func Clear ¶

func Clear[S ~[]T, T any](s S) S

Clear zeros the slice and returns it.

func Insert ¶

func Insert[S ~[]T, T any](s S, index int, item T) []T

Insert inserts an item at an index.

func Pop ¶

func Pop[S ~[]T, T any](sptr *S) T

Pop removes the last item from the slice and returns it. If the slice is empty, it panics. Internally uses slices.Pop to remove the last item.

func Random ¶

func Random[S ~[]T, T any](s S) T

Random returns a random item from the slice, panics if the slice is empty. Internally uses math/rand.Intn to generate a random index.

func Remove ¶

func Remove[S ~[]T, T comparable](s S, item T) S

Remove removes the first occurrence of the item from the slice.

func RemoveAt ¶

func RemoveAt[S ~[]T, T any](s S, index int, n int) S

RemoveAt removes n items at an index, and truncates the slice.

func ShiftLeft ¶

func ShiftLeft[S ~[]T, T any](s S, n int) S

ShiftLeft shifts the slice left by n, and returns the truncated slice.

func Shuffle ¶

func Shuffle[S ~[]T, T any](s S)

Shuffle pseudo-randomizes the order of elements using rand.Shuffle.

func SortLess ¶

func SortLess[S ~[]T, T any](s S, less func(a, b T) bool)

SortLess sorts a slice.

func Truncate ¶

func Truncate[S ~[]T, T any](s S) S

Truncate clears and truncates the slice, returns nil if the slice is nil.

Usage:

s := []int{1, 2, 3}
s = slices2.Truncate(s)
