# std::optional<T>::~optional

From cppreference.com
< cpp‎ | utility‎ | optional

~optional(); |  | (since C++17)

If the object contains a value and the type `T` is not trivially destructible (see std::is_trivially_destructible), destroys the contained value by calling its destructor, as if by value().T::~T().

Otherwise, does nothing.

### Notes

If `T` is trivially-destructible, then this destructor is also trivial, so `optional<T>` is also trivially-destructible.
