Struct qcell::LCell

pub struct LCell<'id, T: ?Sized> { /* fields omitted */ }

Cell whose contents are owned (for borrowing purposes) by a LCellOwner.

To borrow from this cell, use the borrowing calls on the LCellOwner instance that owns it, i.e. that shares the same Rust lifetime.

See also crate documentation.

Implementations

impl<'id, T> LCell<'id, T>

pub fn new(value: T) -> LCell<'id, T>

Create a new LCell. The owner of this cell is inferred by Rust from the context. So the owner lifetime is whatever lifetime is required by the first use of the new LCell.

impl<'id, T: ?Sized> LCell<'id, T>

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

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

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

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