Implementations

impl<T> RcCount<T>

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

pub fn from_weak(weak: &Weak<T>) -> Self

Trait Implementations

impl<T: 'static> Count for RcCount<T>

type Token<'a> = Token<'a, RcCount<T>> where Self: 'a

The token type minted by this counter.

fn get(&self) -> Self::Token<'static>

Acquire one counted reference and return a linear token for it.

fn put<'a>(&'a self, t: Self::Token<'a>) -> bool

Return (consume) a previously acquired token. Returns true if the count is now zero.
