Detailed Description

template<typename TSlot, typename... TArgs>
class wamp::SimpleCoroEventUnpacker< TSlot, TArgs >

Wrapper around an event slot which automatically unpacks positional payload arguments.

The wamp::simpleCoroEvent convenience function should be used to construct instances of SimpleCoroEventUnpacker. This class differs from CoroEventUnpacker in that the slot type is not expected to take an Event as the first parameter.

See also: wamp::simpleCoroEvent; Simple Coroutine Event Slots

Template Parameters

TSlot	Function type to be wrapped. Must have the signature `void function(TArgs..., boost::asio::yield_context)`.
TArgs	List of static types the event slot expects as arguments preceding the `boost::asio::yield_context` parameter.

Member Function Documentation

◆ operator()()

template<typename S , typename... A>

void wamp::SimpleCoroEventUnpacker< S, A >::operator() ( Event event ) const

Spawns a new coroutine and executes the stored event slot.

The coroutine will be spawned using event.executor(). The event.args() positional arguments will be unpacked and passed to the stored event slot as parameters.

◆ simpleCoroEvent()

template<typename... TArgs, typename TSlot >

SimpleCoroEventUnpacker< DecayedSlot< TSlot >, TArgs... > simpleCoroEvent ( TSlot && slot )

Converts an unpacked event slot into a regular slot than can be passed to Session::subscribe. This function differs from unpackedCoroEvent in that the slot type is not expected to take an Event as the first parameter.

See also: Simple Coroutine Event Slots

Returns: An SimpleCoroEventUnpacker that wraps the the given slot.

Template Parameters

TArgs	List of static types the event slot expects as arguments, preceding the `boost::asio::yield_context` parameter.
TSlot	(deduced) Function type to be converted. Must have the signature `void function(TArgs..., boost::asio::yield_context)`.
