WebBoost.Asio provides a complete implementation of the proposed standard executors, as described in P0443r13, P1348r0, and P1393r0 . Just as with executors under the Networking TS model, a standard executor represents a policy as to how, when, and where a piece of code should be executed. Most existing code should continue to work with …

WebThis completion handler is invoked with the result of the coroutine once it has finished. In the above example we pass a completion token type, boost:: asio:: detached, which is used to explicitly ignore the result of an asynchronous operation. In this example the body of the coroutine is implemented in the echo function.

Webdefer (1 of 3 overloads) Submits a completion token or function object for execution. template< typename CompletionToken> DEDUCED defer ( CompletionToken && token); This function submits an object for execution using the object's associated executor. The function object is queued for execution, and is never called from the current thread prior ... WebThe deferred, completion token takes a call to an asynchronous operation's initiating function and turns it into a function object that accepts a completion token. For example: auto deferred_op = timer. async_wait (boost:: asio:: deferred);... std:: move (deferred_op)([](boost:: system:: error_code ec){...}); or:
WebThe deferred_t class is used to indicate that an asynchronous operation should return a function object which is itself an initiation function. A deferred_t object may be passed as a completion token to an asynchronous operation, typically using the special value boost::asio::deferred. For example: The initiating function (async_read_some in ...
