Struct scell::SCell

pub struct SCell<T: ?Sized>(_);

A smart container for objects in recursive data structures

This container contains Rc and therefore clone() will create a new reference to the same instance.

Methods

impl<T> SCell<T>

fn new(t: T) -> Self

impl<T: ?Sized> SCell<T>

fn borrow(&self) -> Ref<T>

fn borrow_mut(&self) -> RefMut<T>

Trait Implementations

impl<T: Default + ?Sized> Default for SCell<T>
