std only.Expand description
A marker trait representing types where a shared reference is considered unwind safe.
This trait is namely not implemented by UnsafeCell, the root of all
interior mutability.
This is a “helper marker trait” used to provide impl blocks for the
UnwindSafe trait, for more information see that documentation.
