类模板coroutine_handle能用于指代暂停或执行的协程。coroutine_handle的每个特化均为字面类型(LiteralType)。 1)主模板,可从Promise类型的承诺对象创建。 2)特化std::coroutine_handle<void>是其他特化的公开基类。它保有协程柄的底层地址。 3)特化std::coroutine_handle<std::noop_coroutine_promise>指代无操作协程。

This conversion function converts a std::coroutine_handle<Promise> value to a std::coroutine_handle<> holding the same underlying address. It effectively erases the promise type. Parameters (none) Return value std::coroutine_handle<>::from_address(address()). See also operator==operator<=...
但是实际接入SDK的过程中我们有相当一部分类型相同但是接入流程不同的情况，再加上现在各大编译器也都...

struct hash<std::coroutine_handle<Promise>>; (since C++20) The template specialization of std::hash for std::coroutine_handle allows users to obtain hashes of objects of type std::coroutine_handle<P>. operator() of the specialization is noexcept. Example This section is incompleteReason:...
