Detailed Description

template<typename TSlot, typename TResult, typename... TArgs>
class wamp::SimpleCoroInvocationUnpacker< TSlot, TResult, TArgs >

Wrapper around a call slot which automatically unpacks positional payload arguments.

The wamp::simpleCoroRpc convenience function should be used to construct instances of SimpleCoroInvocationUnpacker. This class differs from CoroInvocationUnpacker in that the slot type returns TResult and does not take an Invocation as the first parameter. The slot cannot defer the outcome of the RPC and must return a result immediately (or throw a wamp::Error).

Template Parameters

TSlot	Function type to be wrapped. Must have the signature `TResult function(TArgs..., boost::asio::yield_context)`.
TResult	The static result type returned by the slot (may be `void`).
TArgs	List of static types the call slot expects as arguments, preceding the `boost::asio::yield_context` argument.

Member Function Documentation

◆ operator()()

template<typename S , typename R , typename... A>

Outcome wamp::SimpleCoroInvocationUnpacker< S, R, A >::operator() ( Invocation inv ) const

Spawns a new coroutine and executes the stored call slot.

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

◆ simpleCoroRpc()

template<typename TResult , typename... TArgs, typename TSlot >

SimpleCoroInvocationUnpacker< DecayedSlot< TSlot >, TResult, TArgs... > simpleCoroRpc ( TSlot && slot )

Converts an unpacked call slot into a regular slot than can be passed to Session::enroll. This function differs from unpackedCoroRpc in that the slot type returns TResult and is not expected to take an Invocation as the first parameter.

See also: Simple Coroutine Call Slots

Returns: A SimpleCoroInvocationUnpacker that wraps the the given slot.

Template Parameters

TArgs	List of static types the call slot expects as arguments, preceding the `boost::asio::yield_context` argument.
TResult	The static result type returned by the slot (may be `void`).
TSlot	(deduced) Function type to be converted. Must have the signature `TResult function(TArgs..., boost::asio::yield_context)`.
