# Trait std::panic::RefUnwindSafe 1.9.0 [−] [src]

    pub 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.

## Implementors

- `impl<T: ?Sized> !RefUnwindSafe for UnsafeCell<T>`
- `impl<T> RefUnwindSafe for AssertUnwindSafe<T>`
- `impl<T: ?Sized> RefUnwindSafe for Mutex<T>`
- `impl<T: ?Sized> RefUnwindSafe for RwLock<T>`

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)
