as_default_on [static] |
Function helper to adapt an I/O object to use deferred_t as its default completion token type. |
deferred_t [constructor] |
Default constructor. |
Creates a new deferred from a function. |

values [static] |
Returns a deferred operation that returns the provided values. |
when [static] |
Creates a conditional object for branching deferred operations. |
The experimental::deferred_t
class is used to indicate
that an asynchronous operation should return a function object which is
itself an initiation function. A experimental::deferred_t
object may be passed
as a completion token to an asynchronous operation, typically using the
special value asio::deferred
. For example:
auto my_sender = my_socket.async_read_some(my_buffer, asio::experimental::deferred);
The initiating function (async_read_some in the above example) returns a function object that will lazily initiate the operation.
