Implementations§

source§

impl<T: Send> Swapper<T>

source

pub fn swap(&self, our_ref: &mut T) -> Result<(), SwapError>

Swap data.

If the other half of the swap pair is blocked waiting to swap, then it swaps ownership of the data, then unblocks the other thread. Otherwise it blocks waiting to swap.
