Typedefs
template<typename... Args>
using	CeresEngine::Async = cti::continuable< Args... >
	Defines a non-copyable continuation type which uses the function2 backend for type erasure.
template<typename... Args>
using	CeresEngine::Promise = cti::promise< Args... >
	Defines a non-copyable promise type which is using the function2 backend for type erasure.
template<typename... Args>
using	CeresEngine::AsyncResult = cti::result< Args... >
	The result class can carry the three kinds of results an asynchronous operation possibly can return, it's implemented in a variant like data structure which is also specialized to hold arbitrary arguments.

Functions
template<typename... Args, typename Continuation >
constexpr auto	CeresEngine::async (Continuation &&continuation)
	Creates an Async from a promise/callback taking function.
template<typename... Args>
auto	CeresEngine::async_ready (Args &&... args)
	Returns a continuable_base with no result which instantly resolves the promise with no values.
template<typename... Args, typename Exception >
constexpr auto	CeresEngine::async_except (Exception &&exception)
	Returns a continuable_base with the parameterized result which instantly resolves the promise with the given error type.
template<typename Mapper , typename... T>
decltype(auto)	CeresEngine::async_map (Mapper &&mapper, T &&... pack)
	Maps the pack with the given mapper.
template<typename... T>
constexpr decltype(auto)	CeresEngine::async_spread (T &&... args)
	Indicate that the result shall be spread across the parent container if possible.
template<typename Mapper , typename... T>
void	CeresEngine::async_traverse (Mapper &&mapper, T &&... pack)
	Traverses the pack with the given visitor.
auto	CeresEngine::wait ()
	Awaits (and blocks) until the continuation has finished running.
template<class Rep , class Period >
auto	CeresEngine::wait (const TTimeInterval< Rep, Period > &timeout)
	Awaits (and blocks) until the continuation has finished running.
template<class Clock , class Duration >
auto	CeresEngine::wait (const TDate< Clock, Duration > &timeout)
	Awaits (and blocks) until the continuation has finished running.

Variables
constexpr cti::use_continuable_raw_t	CeresEngine::useContinuable {}
	Special value for instance of use_continuable_raw_t which doesn't perform remapping of asio error codes and rethrows the raw error code.
