Functions

func Group

func Group[K comparable, V any](s []V, key func(V) K) map[K][]V

Group returns a new non-nil map containing the elements of s grouped by the keys returned from the key func.

func KeySlice

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

KeySlice returns the keys of the map M, like slices.Collect(maps.Keys(m)).

func SameKeys

func SameKeys[K comparable, V1, V2 any](x map[K]V1, y map[K]V2) bool

SameKeys reports whether x and y have equal sets of keys.

func Sorted

func Sorted[M ~map[K]V, K cmp.Ordered, V any](m M) iter.Seq2[K, V]

Sorted returns an iterator over the entries of m in key order.

func SortedFunc

func SortedFunc[M ~map[K]V, K comparable, V any](m M, cmp func(x, y K) int) iter.Seq2[K, V]

SortedFunc returns an iterator over the entries of m in the key order determined by cmp.

func ValueSlice

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

ValueSlice returns the values of the map M, like slices.Collect(maps.Values(m)).
