A type-invariant immutable Map of key type K, and value type V. In the Map, each key has exactly one value, and the Map cannot contain duplicate keys. See the Map documentation and the RMap API documentation

A mutable RMap builder used to efficiently create new immutable instances. See the Map documentation and the RMap.Builder API documentation

A context instance for RMap implementations that acts as a factory for every instance of this type of collection.

A non-empty type-invariant immutable Map of key type K, and value type V. In the Map, each key has exactly one value, and the Map cannot contain duplicate keys. See the Map documentation and the RMap API documentation

Utility interface that provides higher-kinded types for this collection.
