### Dispatch Class API Documentation

```APIDOC
class Dispatch:
    """A method dispatcher class allowing for multiple implementations of a function. Each implementation is associated to a specific input type.

    Implementations are registered with the annotation :meth:`~wolframclient.utils.dispatch.Dispatch.dispatch`.

    The Dispatch class is callable, it behaves as a function that uses the implementation corresponding to the input parameter.

    When a type is a subtype, the type and its parents are checked in the order given by :data:`__mro__` (method resolution order).

    *Example:* method :meth:`~wolframclient.utils.dispatch.Dispatch.resolve` applied to an instance of :class:`collections.OrderedDict`,
    check for the first implementation to match with :class:`collections.OrderedDict`, then with :class:`dict`, and ultimately to :data:`object`.

    Once the mapping is determined, it is cached for later use.

            @dispatcher.dispatch((bytes, bytearray))
            def my_func(...)

        Implementation must be unique. By default, registering the same combination of types will raise an error. Set `replace_existing` to :data:`True` to update the current mapping. Or, set `keep_existing` to :data:`True` to ignore duplicate registration and keep the existing mapping.
