Types ¶
type Map ¶
type Map struct {
// contains filtered or unexported fields
}
Map is a two-level locking map which synchronizes access to the map in addition to synchronizing access to the values within the map. Useful for mutating values in-place.
The zero Map is valid and empty.
func (*Map) Load ¶
Load looks up the value of key k and executes f under the protection of said value's lock. While f executes, it is guaranteed that k will not be deleted from the map. Returns false if k was not found.
func (*Map) Range ¶
Range interates over the Map and execs f until f returns false.
