template <typename Callable>class StdFunctionAdaptor
Defined at line 508 of file ../../third_party/googletest/src/googlemock/include/gmock/gmock-actions.h
An adaptor that wraps a callable that is compatible with our signature and
being invoked as an rvalue reference so that it can be used as an
StdFunctionAdaptor. This throws away type safety, but that's fine because
this is only used by WillOnce, which we know calls at most once.
Once we have something like std::move_only_function from C++23, we can do
away with this.

template <typename... ArgRefs>internal::call_result_t<Callable, ArgRefs...> operator() (ArgRefs &&... args)Rather than explicitly returning Result, we return whatever the wrapped
callable returns. This allows for compatibility with existing uses like
the following, when the mocked function returns void:
EXPECT_CALL(mock_fn_, Call)
.WillOnce([
&
] {
[...]
return 0;
});
Such a callable can be turned into std::function
<void
()>. If we use an
explicit return type of Result here then it *doesn't* work with
std::function, because we'll get a "void function should not return a
value" error.
We need not worry about incompatible result types because the SFINAE on
OnceAction already checks this for us. std::is_invocable_r_v itself makes
the same allowance for void result types.
