Trait TryGuardedMut 

pub trait TryGuardedMut<T>: GuardedMut<T>
where
    T: ?Sized,
{
    type Error<'a>: Debug
       where Self: 'a;

    // Required method
    fn try_get_mut<'a>(&'a self) -> Result<Self::GuardMut<'a>, Self::Error<'a>>;
}

Required Associated Types

type Error<'a>: Debug where Self: 'a

Required Methods

fn try_get_mut<'a>(&'a self) -> Result<Self::GuardMut<'a>, Self::Error<'a>>

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.
