Struct Arc

Source
pub struct Arc<T: ?Sized> { /* private fields */ }
Expand description

A thread-safe reference-counting pointer. ‘Arc’ stands for ‘Atomically Reference Counted’.

Implementations§

Source§

impl<T> Arc<T>

Source

pub fn new(data: T) -> Self

Constructs a new Arc<T>.

Source

pub fn from_rc(rc: Rc<T>) -> Self

Converts an Rc<T> to Arc<T>. This changes its count to start using atomic access, even in other outstanding Rc<T> references to the same underlying object.
