Struct loom::cell::UnsafeCell [−][src]
A checked version of std::cell::UnsafeCell.
Instead of providing a get() API, this version of UnsafeCell provides
with and with_mut. Both functions take a closure in order to track the
start and end of the access to the underlying cell.
Implementations
impl<T> UnsafeCell<T>[src]
pub fn new(data: T) -> UnsafeCell<T>[src]
Constructs a new instance of UnsafeCell which will wrap the specified value.
pub fn with<F, R>(&self, f: F) -> R where
F: FnOnce(*const T) -> R, [src]
F: FnOnce(*const T) -> R,
Get an immutable pointer to the wrapped value.
Panics
This function will panic if the access is not valid under the Rust memory model.
pub fn with_mut<F, R>(&self, f: F) -> R where
F: FnOnce(*mut T) -> R, [src]
F: FnOnce(*mut T) -> R,
Get a mutable pointer to the wrapped value.
Panics
This function will panic if the access is not valid under the Rust memory model.
