@frozen struct AnyPublisher<Output, Failure> where Failure : Error

A publisher that performs type erasure by wrapping another publisher. ``AnyPublisher`` is a concrete implementation of ``Publisher`` that has no significant properties of its own, and passes through elements and completion values from its upstream publisher. Use ``AnyPublisher`` to wrap a publisher whose type has details you don’t want to expose across API boundaries, such as different modules. Wrapping a ``Subject`` with ``AnyPublisher`` also prevents callers from accessing its ``Subject/send(_:)`` method. When you use type erasure this way, you can change the underlying publisher implementation over time without affecting existing clients. You can use Combine’s ``Publisher/eraseToAnyPublisher()`` operator to wrap a publisher with ``AnyPublisher``.
