Functions

func Clone

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

Clone returns a copy of s

func Contains

func Contains[S ~[]T, T comparable](s S, v T) bool

Contains reports whether v is present in s.

func Equal

func Equal[X ~[]T, Y ~[]T, T comparable](x X, y Y) bool

Equal reports whether two slices are equal: the same length and all elements equal.

func EqualFunc

func EqualFunc[
	X ~[]U,
	Y ~[]V,
	F ~func(U, V) bool,
	U any,
	V any,
](x X, y Y, f F) bool

EqualFunc reports whether two slices are equal using a comparison function on each pair of elements.

func Index

func Index[S ~[]T, T comparable](s S, v T) int

Index returns the index of the first occurrence of v in s, or -1 if not present.

func IndexFunc

func IndexFunc[S ~[]T, F ~func(T) bool, T any](s S, f F) int

IndexFunc returns the first index i satisfying f(s[i]), or -1 if none do.

func LastIndex

func LastIndex[S ~[]T, T comparable](s S, v T) int

LastIndex returns the index of the last occurrence of v in s, or -1 if not present.

func LastIndexFunc

func LastIndexFunc[S ~[]T, F ~func(T) bool, T any](s S, f F) int

LastIndexFunc returns the first index i satisfying f(s[i]), or -1 if none do.

func Map

func Map[
	S ~[]T,
	F ~func(T) U,
	T any,
	U any,
](s S, f F) []U

Map creates a new slice which values mapping from s by function f

func MapAppend[
	D ~[]U,
	S ~[]T,
	F ~func(T) U,
	T any,
	U any,
