Struct tokio::util::rc_cell::RcCell

pub(crate) struct RcCell<T> {
    inner: UnsafeCell<Option<Rc<T>>>,
}

This is exactly like Cell<Option<Rc<T>>>, except that it provides a get method even though Rc is not Copy.

Fields

inner: UnsafeCell<Option<Rc<T>>>

Implementations

impl<T> RcCell<T>

pub(crate) const fn new() -> Self

unsafe fn with_inner<F, R>(&self, f: F) -> R

where F: FnOnce(&mut Option<Rc<T>>) -> R,

Safety: This method may not be called recursively.

pub(crate) fn get(&self) -> Option<Rc<T>>

pub(crate) fn replace(&self, val: Option<Rc<T>>) -> Option<Rc<T>>

pub(crate) fn set(&self, val: Option<Rc<T>>)
