Structs

RcWeak

Struct alloc::rc::Rc[src]

pub struct Rc<T> {
    // some fields omitted
}

Immutable reference counted pointer type

Methods

impl<T> Rc<T>

fn new(value: T) -> Rc<T>

Construct a new reference-counted box

impl<T> Rc<T>

fn downgrade(&self) -> Weak<T>

Downgrade the reference-counted pointer to a weak reference

impl<T: Clone> Rc<T>

fn make_unique<'a>(&'a mut self) -> &'a mut T

Acquires a mutable pointer to the inner contents by guaranteeing that the reference count is one (no sharing is possible).

This is also referred to as a copy-on-write operation because the inner data is cloned if the reference count is greater than one.

Trait Implementations
