DerivedEnvironment

DerivedEnvironment

Use this property wrapper to declare child ComposableEnvironment in a ComposableEnvironment subclass.

@propertyWrapper
public final class DerivedEnvironment<Value> where Value: ComposableEnvironment 

You only need to specify the subclass used and its name. You don't need to instantiate the subclass. For example, if ChildEnvironment is a ComposableEnvironment subclass, you can install a representant in ParentEnvironment as:

class ParentEnvironment: ComposableEnvironment {
  @DerivedEnvironment<ChildEnvironment> var child
}.

This exposes a var child: ChildEnvironment read-only property in the ParentEnvironment. This child environment inherits the current dependencies of all its ancestor. They can be exposed using the Dependency property wrapper.
