RefUnwindSafe in std::panic - Rust
Description: A marker trait representing types where a shared reference is considered unwind safe.

## RefUnwindSafe

# Trait RefUnwindSafe

    pub auto trait RefUnwindSafe { }

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.
