Struct os::sync::up::UPSafeCell

pub struct UPSafeCell<T> {
    inner: RefCell<T>,
}

Wrap a static data structure inside it so that we are able to access it without any unsafe.

We should only use it in uniprocessor.

In order to get mutable reference of inner data, call exclusive_access.

Fields

inner: RefCell<T>

inner data

Implementations
