Struct qcell::TCell

pub struct TCell<Q, T: ?Sized> { /* private fields */ }

This is supported on crate feature std only.

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

To borrow from this cell, use the borrowing calls on the TCellOwner instance that shares the same marker type.

See also crate documentation.

Implementations

impl<Q, T> TCell<Q, T>

pub const fn new(value: T) -> TCell<Q, T>

Create a new TCell owned for borrowing purposes by the TCellOwner derived from the same marker type Q.

impl<Q, T: ?Sized> TCell<Q, T>

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

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

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

Borrow contents of this cell mutably (read-write). Only one TCell 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 TCellOwner::rw2 or TCellOwner::rw3.
