Trait GuardedMut 

pub trait GuardedMut<T>
where
    T: ?Sized,
{
    type GuardMut<'a>: DerefMut<Target = T>
       where Self: 'a;

    // Required method
    fn get_mut<'a>(&'a self) -> Self::GuardMut<'a>;
}

Required Associated Types

type GuardMut<'a>: DerefMut<Target = T> where Self: 'a

Required Methods

fn get_mut<'a>(&'a self) -> Self::GuardMut<'a>

Can panic on exceptional behavior (ex poisoned mutex)

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
