Trait TxnIterator 

pub trait TxnIterator {
    type Item;

    // Required method
    fn next<T>(&mut self, txn: &T) -> Option<Self::Item>
       where T: ReadTxn;

    // Provided method
    fn collect<T, B>(&mut self, txn: &T) -> B
       where T: ReadTxn,
             B: Default + Extend<Self::Item> { ... }
}

Iterator equivalent that can be supplied with transaction when iteration step may need it.
