std::panic::RefUnwindSafe - Rust
Description: API documentation for the Rust `RefUnwindSafe` trait in crate `std`.
Keywords: rust, rustlang, rust-lang, RefUnwindSafe

# 1.9.0[−][src]Trait std::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.
