Trait core::panic::RefUnwindSafe

pub auto trait RefUnwindSafe { }

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.
