$$ This is a pump file for generating file templates. Pump is a python
$$ script that is part of the Google Test suite of utilities. Description
$$ can be found here:
$$
$$ https://github.com/google/googletest/blob/main/googletest/docs/PumpManual.md
$$
$$ MAX_ARITY controls the number of arguments that MockCallback supports.
$$ It is choosen to match the number GMock supports.
$var MAX_ARITY = 10

// Copyright 2017 The Chromium Authors
// Use of this source code is governed by a BSD-style license that can be
// found in the LICENSE file.
// Analogous to GMock's built-in MockFunction, but for base::{Once,
// Repeating}Callback instead of std::function. It takes the full callback type
// as a parameter, so that it can support both OnceCallback and
// RepeatingCallback. Furthermore, this file defines convenience typedefs in the
// form of MockOnceCallback<Signature>, MockRepeatingCallback<Signature>,
// MockOnceClosure and MockRepeatingClosure.
//
// Use:
// using FooCallback = base::RepeatingCallback<int(std::string)>;
//
// TEST(FooTest, RunsCallbackWithBarArgument) {
// base::MockCallback<FooCallback> callback;
// EXPECT_CALL(callback, Run("bar")).WillOnce(Return(1));
// Foo(callback.Get());
// }
//
// Or equivalently:
//
// TEST(FooTest, RunsCallbackWithBarArgument) {
// base::MockRepeatingCallback<int(std::string)> callback;
// EXPECT_CALL(callback, Run("bar")).WillOnce(Return(1));
// Foo(callback.Get());
// }
//
//
// Can be used with StrictMock and NiceMock. Caller must ensure that it outlives
// any base::{Once, Repeating}Callback obtained from it.
