Functions

func Copy

func Copy[M ~map[K]V, K comparable, V any](src *Map[K, V], dst M)

Copy copies all key/value pairs in src adding them to dst. When a key in src is already present in dst, the value in dst will be overwritten by the value associated with the key in src.

Types

type Map

type Map[K comparable, V any] struct {
	// contains filtered or unexported fields
}

func Clone

func Clone[M ~map[K]V, K comparable, V any](src M) *Map[K, V]

Clone returns a copy of src. this is a shallow clone the new keys and values are set using ordinary assignment.
