• func Init[M ~map[K]V, K comparable, V any](m M) M
• func SetDefault[M ~map[K]V, K comparable, V any](m M, k K, defaultValue V) V

Functions

func Init

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

Init clears m and returns m if m != nil or returns a new map otherwise.

func SetDefault

func SetDefault[M ~map[K]V, K comparable, V any](m M, k K, defaultValue V) V

SetDefault returns m[k] or if m does not contain k, then SetDefault sets m[k] to defaultValue and returns defaultValue.

func Sorted

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

Sorted iterates over a map in sorted order.

func SortedKeys

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

SortedKeys returns a slice of the map's keys in sorted order.
