Construct default deleter
Constructs a default_delete object.
This is a stateless class where the constructor performs no operation.
The second constructor only participates in overload resolution if U* is implicitly convertible to T* (where T is default_delete's template parameter).
Parameters
- del
- A default_deleter object of some type whose pointer is implicitly convertible to T*.
