Function libpijul::apply_change_arc

pub fn apply_change_arc<T: MutTxnT, P: ChangeStore>(
    changes: &P, 
    txn: &ArcTxn<T>, 
    channel: &ChannelRef<T>, 
    hash: &Hash
) -> Result<(u64, Merkle), ApplyError<P::Error, T::GraphError>>

Same as [apply_change], but with a wrapped txn and channel.
