Struct qcell::QCell

pub struct QCell<T: ?Sized> { /* fields omitted */ }

Cell whose contents is owned (for borrowing purposes) by a QCellOwner.

To borrow from this cell, use the borrowing calls on QCellOwner instance that was used to create it. See crate documentation.

Implementations

impl<T> QCell<T>

pub const fn new(owner: &QCellOwner, value: T) -> QCell<T>

Create a new QCell owned for borrowing purposes by the given QCellOwner

impl<T: ?Sized> QCell<T>

pub fn ro<'a>(&'a self, owner: &'a QCellOwner) -> &'a T

Borrow contents of this cell immutably (read-only). Many QCell instances can be borrowed immutably at the same time from the same owner.

pub fn rw<'a>(&'a self, owner: &'a mut QCellOwner) -> &'a mut T

Borrow contents of this cell mutably (read-write). Only one QCell at a time can be borrowed from the owner using this call. The returned reference must go out of scope before another can be borrowed. To mutably borrow from two or three cells at the same time, see QCellOwner::rw2 or QCellOwner::rw3.
