Overview

Package slices provides generic higher-order functions over slices of values.

Functions

func FlatMap

func FlatMap[X any, Y any](f func(X) []Y, xs []X) []Y

FlatMap applies function "f : X => []Y" to each value of the input slice, and returns a new slice of each output in sequence. The output sequence is "flattened" so that each slice returned by f is concatenated into a single slice.

If the input slice is a nil slice, the return value is also a nil slice. If f returns a nil slice, it is not included in the output.

For a lazy version, see the iter package.

func Map

func Map[X any, Y any](f func(X) Y, xs []X) []Y

Map applies function "f : X => Y" to each value of the input slice, and returns a new slice of each output in sequence.

If the input slice is a nil slice, the return value is also a nil slice.

For a lazy version, see the iter package.
