Overview

Package util provides various helper functions.

I know that Map/Reduce/Filter isn't idiomatic Go, but I still find them very useful!

Index

• func Contains[T comparable](l []T, query T) bool
• func Filter[T any](l []T, f func(T) bool) []T
• func ForEach[T any](l []T, f func(T))
• func Map[T any, R any](l []T, f func(T) R) []R
• func Reduce[T any, R any](l []T, f func(R, T) R, acc R) R
• func Remove[T comparable](l []T, toRemove T) []T

Functions

func Contains

func Contains[T comparable](l []T, query T) bool

Contains checks if a slice contains a given element.

func Filter

func Filter[T any](l []T, f func(T) bool) []T

Filter iterates over a slice and returns a slice containing only the elements for which the predicate is true.

func ForEach

func ForEach[T any](l []T, f func(T))

ForEach applies a function to each element in a slice.

func Map

func Map[T any, R any](l []T, f func(T) R) []R

Map creates a new slice from the result of calling a function on each element of an input slice.

func Reduce

func Reduce[T any, R any](l []T, f func(R, T) R, acc R) R

Reduce applies an accumulator function from left to right on a slice with a given initial value.

func Remove

func Remove[T comparable](l []T, toRemove T) []T

Remove removes all instances of an element from a slice.
