/// A [`wiremock`] [`MockServer`] along with useful methods to help mocking
/// Matrix client-server API endpoints easily.
///
/// It implements mock endpoints, limiting the shared code as much as possible,
/// so the mocks are still flexible to use as scoped/unscoped mounts, named, and
/// so on.
///
/// It works like this:
///
/// * start by saying which endpoint you'd like to mock, e.g.
///   [`Self::mock_room_send()`]. This returns a specialized [`MockEndpoint`]
///   data structure, with its own impl. For this example, it's
///   `MockEndpoint<RoomSendEndpoint>`.
/// * configure the response on the endpoint-specific mock data structure. For
///   instance, if you want the sending to result in a transient failure, call
///   [`MockEndpoint::error500`]; if you want it to succeed and return the event
///   `$42`, call [`MockEndpoint::ok()`]. It's still possible to call
///   [`MockEndpoint::respond_with()`], as we do with wiremock MockBuilder, for
///   maximum flexibility when the helpers aren't sufficient.
/// * once the endpoint's response is configured, for any mock builder, you get
///   a [`MatrixMock`]; this is a plain [`wiremock::Mock`] with the server
///   curried, so one doesn't have to pass it around when calling
///   [`MatrixMock::mount()`] or [`MatrixMock::mount_as_scoped()`]. As such, it
///   mostly defers its implementations to [`wiremock::Mock`] under the hood.
///
