func Clear
func Clear[M ~map[K]V, K comparable, V any](m M)
Clear removes all entries from m, leaving it empty.
func Clone
func Clone[M ~map[K]V, K comparable, V any](m M) M
Clone returns a copy of m. This is a shallow clone: the new keys and values are set using ordinary assignment.
func Copy
func Copy[M ~map[K]V, K comparable, V any](dst, src 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.
func DeleteFunc
func DeleteFunc[M ~map[K]V, K comparable, V any](m M, del func(K, V) bool)
DeleteFunc deletes any key/value pairs from m for which del returns true.
func Equal
func Equal[M1, M2 ~map[K]V, K, V comparable](m1 M1, m2 M2) bool
Equal reports whether two maps contain the same key/value pairs. Values are compared using ==.
func EqualFunc
func EqualFunc[M1 ~map[K]V1, M2 ~map[K]V2, K comparable, V1, V2 any](m1 M1, m2 M2, eq func(V1, V2) bool) bool
EqualFunc is like Equal, but compares values using eq. Keys are still compared with ==.
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 in an indeterminate order.
func Values
func Values[M ~map[K]V, K comparable, V any](m M) []V
Values returns the values of the map m. The values will be in an indeterminate order.

Functions ¶
func Clear ¶
func Clear[M ~map[K]V, K comparable, V any](m M)
Clear removes all entries from m, leaving it empty.
func Clone ¶
func Clone[M ~map[K]V, K comparable, V any](m M) M
Clone returns a copy of m. This is a shallow clone: the new keys and values are set using ordinary assignment.
func Copy ¶
func Copy[M1 ~map[K]V, M2 ~map[K]V, K comparable, V any](dst M1, src M2)
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.
func DeleteFunc ¶
func DeleteFunc[M ~map[K]V, K comparable, V any](m M, del func(K, V) bool)
DeleteFunc deletes any key/value pairs from m for which del returns true.
func Equal ¶
func Equal[M1, M2 ~map[K]V, K, V comparable](m1 M1, m2 M2) bool
Equal reports whether two maps contain the same key/value pairs. Values are compared using ==.
func EqualFunc ¶
func EqualFunc[M1 ~map[K]V1, M2 ~map[K]V2, K comparable, V1, V2 any](m1 M1, m2 M2, eq func(V1, V2) bool) bool
EqualFunc is like Equal, but compares values using eq. Keys are still compared with ==.
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 in an indeterminate order.
func Values ¶
func Values[M ~map[K]V, K comparable, V any](m M) []V
Values returns the values of the map m. The values will be in an indeterminate order.
