Source 
pub struct CompareExchangeError<'g, T: ?Sized + Pointable, P: Pointer<T>> {
    pub current: Shared<'g, T>,
    pub new: P,
}
Expand description

The error returned on failed compare-and-swap operation.

Fields§

§current: Shared<'g, T>

The value in the atomic pointer at the time of the failed operation.

§new: P
