Detailed Description

template<typename Value = void>
class xentara::workbench::bindings::Undefined< Value >

A value that allows assigning and initializing undefined value for ValueOrUndefined.

This type is used in a similar way to std::unexpected, except that it is used for ValueOrUndefined objects rather than std::expected objects.
