template<typename Data, typename Hint>
cti::promise_base class

The promise_base makes it possible to resolve an asynchronous continuable through it's result or through an error type.

Contents

Use the promise type defined in continuable/continuable_types.hpp, in order to use this class.

If we want to resolve the promise_base trough the call operator, and we want to resolve it through an exception, we must call it with a dispatch_error_tag as first and the exception as second argument. Additionally the promise is resolveable only through its call operator when invoked as an r-value.

Constructors, destructors, conversion operators

promise_base(Data data) explicit
Constructor accepting the data object.
template<typename OData, std::enable_if_t<std::is_convertible<std::decay_t<OData>, Data>::value>* = nullptr>
promise_base(OData&& data)
Constructor accepting any object convertible to the data object.
