Struct Documentation

template<typename E>
struct concore::v1::as_sender

Wrapper that transforms a receiver into a functor.

The receiver should model

Template Parameters

• R: The type of the receiver

This will store a reference to the receiver; the receiver must not get out of scope.

When this functor is called set_value() will be called on the receiver. If an exception is thrown, the set_error() function is called.

If the functor is never called, the destructor of this object will call set_done().

This types models the sender concept.
