Struct loom::cell::UnsafeCell

pub struct UnsafeCell<T> { /* fields omitted */ }

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>

pub fn new(data: T) -> UnsafeCell<T>

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, 

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, 

Get a mutable pointer to the wrapped value.

Panics

This function will panic if the access is not valid under the Rust memory model.
