Struct core::ptr::Shared [−] [src]

pub struct Shared<T: ?Sized> {
    pointer: NonZero<*const T>,
    _marker: PhantomData<T>,
}

Unstable (shared #27730)
: needs an RFC to flesh out design

A wrapper around a raw *mut T that indicates that the possessor of this wrapper has shared ownership of the referent. Useful for building abstractions like Rc<T> or Arc<T>, which internally use raw pointers to manage the memory that they own.

Fields

`pointer`	Unstable (`shared` #27730) : needs an RFC to flesh out design
`_marker`	Unstable (`shared` #27730) : needs an RFC to flesh out design

Methods

`impl<T: ?Sized> Shared<T>`

`unsafe fn new(ptr: *mut T) -> Self`

Unstable (shared #27730)

Creates a new Shared.

Trait Implementations

`impl<T: ?Sized> !Send for Shared<T>`

Shared pointers are not Send because the data they reference may be aliased.

`impl<T: ?Sized> !Sync for Shared<T>`

Shared pointers are not Sync because the data they reference may be aliased.
