cppcoreguidelines-avoid-reference-coroutine-parameters¶
Warns when a coroutine accepts reference parameters. After a coroutine suspend point, references could be dangling and no longer valid. Instead, pass parameters as values.
Examples:
std::future<int> someCoroutine(int& val) {
co_await ...;
// When the coroutine is resumed, 'val' might no longer be valid.
if (val) ...
}
This check implements CppCoreGuideline CP.53.
