| ~optional(); | | (since C++17) (constexpr since C++20) | | ------------- | | ------------------------------------- |

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.

[edit] Notes

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

The following behavior-changing defect reports were applied retroactively to previously published C++ standards.
