Detailed Description
template<typename T>
class docwire::errors::nested< T >
A template class that simplifies the creation of nested exceptions.
In C++, creating a nested exception using std::nested_exception requires throwing and catching an inner exception, and then using std::throw_with_nested to create the nested exception. This template class, together with make_nested macro provides a more straightforward way to create nested exceptions without the need for throwing and catching.
- Template Parameters
-
T The type of the outer exception.

Constructs a nested object from an rvalue reference to an object of type T.
Outer exception is constructed from the rvalue reference. Inner exception is captured using std::current_exception() and stored in the std::nested_exception base class.
- Parameters
-
t An rvalue reference to an object of type T.

Constructs a nested object from a const lvalue reference to an object of type T.
Outer exception is constructed from the lvalue reference. exception is captured using std::current_exception() and stored in the std::nested_exception base class.
- Parameters
-
t A const lvalue reference to an object of type T.
