Functions

func Difference

func Difference[M ~map[K]V, K comparable, V any](a, b M) M

Difference returns all the elements in 'a' that are not in 'b'.

func Filter

func Filter[M ~map[K]V, K comparable, V any](m M, p ...func(k K, v V) bool) M

Filter removes all key/value pairs in the given map that do not match the given predicates.

NOTE: Providing no predicates results in a no-op.

func Keys

func Keys[M ~map[K]V, K comparable, V any](m M, p ...func(k K, v V) bool) []K

Keys returns the keys from the given map.

NOTE: When provided with one or more predicates, only returns keys which match all predicates.

func Values

func Values[M ~map[K]V, K comparable, V any](m M, p ...func(k K, v V) bool) []V

Values returns the values from the given map.

NOTE: When provided with one or more predicates, only returns values which match all predicates.
