Detailed Description

template<class E>
class Aleph::bad_expected_access< E >

Exception thrown by expected::value() when no value is held.

Thrown when calling value() on an expected in the error state. Carries a copy of the stored error for inspection.

Template Parameters

E	Error type (must be movable).

Thread Safety

Exception objects may be copied across threads; what() and error() are safe to call concurrently on the same object.
