Trait redox_buffer_pool::GuardableExclusive

pub unsafe trait GuardableExclusive<G, T>: Guardable<G, T> where
    G: Guard,
    T: ?Sized, {
    fn try_get_data_mut(&mut self) -> Option<&mut T>;
}

A trait for guardable types, that are also non-aliasable (while there is a guard), and mutable. This trait is intended to be implemented for any type of collection with exclusive access to the inner data, e.g. Box<[u8]>, Vec<u8>, etc.

Safety

This requires that all safety guarantees of Guardable are upheld, but also that the memory must not be retrievable while the guard is inserted.

Required methods

fn try_get_data_mut(&mut self) -> Option<&mut T>

Attempt to retrieve the inner mutable data, so long as there is not a guard.
