Destructible

C++ concepts: Destructible

Specifies that an instance of the type can be destructed.

Requirements

The type T satisfies Destructible if.

Given.

• u, a expression of type T

The following expressions must be valid and have their specified effects.

Notes

Destructors are called implicitly at the end of object lifetime such as when leaving scope or by the delete-expression. Explicit destructor call as shown in the type requirement table is rare.

Thanks to pseudo destructor call, all scalar types meet the requirement of Destructible, while array types and reference types do not. Note that std::is_destructible allows arrays and reference types.
