Construct a yield context to represent the specified coroutine.

Return a yield context that sets the specified error_code. |
The basic_yield_context
class is used to represent the currently executing stackful coroutine. A
basic_yield_context
may be passed as a handler to an asynchronous operation. For example:
template <typename Handler> void my_coroutine(basic_yield_context<Handler> yield) { ... std::size_t n = my_socket.async_read_some(buffer, yield); ... }
The initiating function (async_read_some in the above example) suspends the current coroutine. The coroutine is resumed when the asynchronous operation completes, and the result of the operation is returned.
