The def-id of the destructor method

is_dtorck: bool

🔬 This is a nightly-only experimental API. (rustc_private)

Invoking the destructor of a dtorck type during usual cleanup (e.g. the glue emitted for stack unwinding) requires all lifetimes in the type-structure of adt to strictly outlive the adt value itself.

If adt is not dtorck, then the adt's destructor can be invoked even when there are lifetimes in the type-structure of adt that do not strictly outlive the adt value itself. (This allows programs to make cyclic structures without resorting to unsafe means; see RFCs 769 and 1238).
