Functions

func ChunkBy

func ChunkBy[T any](items []T, chunkSize int) (chunks [][]T)

func Contains

func Contains[T comparable](collection []T, element T) bool

Contains checks if the given element is present in the collection.

func CopyMap

func CopyMap[K, V comparable](m map[K]V) map[K]V

CopyMap creates a new copy of the given map and returns it.

func Filter

func Filter[T any](collection []T, f func(e T, i int) bool) []T

func Keys

func Keys[M ~map[K]V, K comparable, V any](m M) []K

Keys returns the keys of the map m. The keys will be an indeterminate order.

func Map

func Map[T, U any](ts []T, f func(e T, i int) U) []U

Map manipulates a slice and transforms it to a slice of another type.

func MergeMaps

func MergeMaps[M ~map[K]V, K comparable, V any](src ...M) M

MergeMaps merges multiple maps into a single map and returns the merged result.

func OmitByKeys

func OmitByKeys[K comparable, V any](in map[K]V, keys []K) map[K]V

OmitByKeys creates a new map by omitting key-value pairs from the input map based on the specified keys.
