Struct AtomicPtr 

pub struct AtomicPtr<T> { /* private fields */ }

A raw pointer type which can be safely shared between threads.

This type has the same in-memory representation as a *mut T.

Implementations

impl<T> AtomicPtr<T>

pub const fn new(p: *mut T) -> AtomicPtr<T>

Creates a new AtomicPtr.

Examples

use msp430_atomic::AtomicPtr;

let ptr = &mut 5;
let atomic_ptr  = AtomicPtr::new(ptr);

pub fn get_mut(&mut self) -> &mut *mut T

Returns a mutable reference to the underlying pointer.

This is safe because the mutable reference guarantees that no other threads are concurrently accessing the atomic data.

Examples

use msp430_atomic::AtomicPtr;

let mut atomic_ptr = AtomicPtr::new(&mut 10);
*atomic_ptr.get_mut() = &mut 5;
assert_eq!(unsafe { *atomic_ptr.load() }, 5);

pub fn into_inner(self) -> *mut T

Consumes the atomic and returns the contained value.

This is safe because passing self by value guarantees that no other threads are concurrently accessing the atomic data.

Examples

use msp430_atomic::AtomicPtr;

let atomic_ptr = AtomicPtr::new(&mut 5);
assert_eq!(unsafe { *atomic_ptr.into_inner() }, 5);

pub fn load(&self) -> *mut T

Loads a value from the pointer.

Examples

use msp430_atomic::AtomicPtr;

let ptr = &mut 5;
let some_ptr  = AtomicPtr::new(ptr);

let value = some_ptr.load();

pub fn store(&self, ptr: *mut T)

Stores a value into the pointer.

Examples

use msp430_atomic::AtomicPtr;

let ptr = &mut 5;
let some_ptr  = AtomicPtr::new(ptr);

let other_ptr = &mut 10;

some_ptr.store(other_ptr);
