Trait arc_cell::AtomicCellStorable

pub unsafe trait AtomicCellStorable {
    const TAKEN_VALUE: usize;

    fn into_value(self) -> usize;
    unsafe fn from_value(value: usize) -> Self;
}

It is up to the implementer to ensure this is safe to implement.

from_value and into_value should never panic nor return TAKEN_VALUE. It is also up to the implementer to ensure that if T implements Clone, its implementation of clone() will never panic.

Associated Constants

const TAKEN_VALUE: usize

A sentinel value that a valid instance should never occupy.

Required methods

fn into_value(self) -> usize

Convert an instance into a raw value, transferring ownership.

unsafe fn from_value(value: usize) -> Self

Convert a raw value back into an instance.
