Detailed Description

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

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

The wamp::unpackedCoroEvent convenience function should be used to construct instances of CoroEventUnpacker.

Template Parameters

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

Member Function Documentation

◆ operator()()

template<typename S , typename... A>

void wamp::CoroEventUnpacker< 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 additional parameters.

◆ unpackedCoroEvent()

template<typename... TArgs, typename TSlot >

CoroEventUnpacker< DecayedSlot< TSlot >, TArgs... > unpackedCoroEvent ( TSlot && slot )

Converts an unpacked event slot into a regular slot than can be passed to Session::subscribe. The slot will be executed within the context of a coroutine and will be given a boost::asio::yield_context as the last call argument.

See also: Unpacked Coroutine Event Slots

Returns: An CoroEventUnpacker that wraps the the given slot.

Template Parameters

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