The long equivalent of Traversable.drop
A foldLeft operation that can be terminated without processing the entire collection.
A foldLeft operation that can be terminated without processing the entire collection.
Unlike a normal fold, the function passed to limitFold returns a scalax.io.FoldResult which both provides the value that is to be passed to the next stage of the fold as well as represents if the fold should continue or terminate.
the value to seed the operation with. IE the value that is passed as the accumulator for the first value of the fold operation
the operation that combines the current and previous versions. The input is the (acc,next) where acc is the result from the previous call and next is the next value in the collection to be processed. The return value of the op is Either scalax.io.Continue or scalax.io.End indicating if the process should continue to next element or terminate, returning the value contained in the result object
the last value contained in the scalax.io.FoldResult which was returned by op

Use the underlying iterator for this traversable.
Use the underlying iterator for this traversable.
if the iterator is returned
withIterator catches all exceptions and calls the error handler to handle the exceptions So exceptions must not be thrown in f as control flow exceptions.
,If the iterator is returned from this block an exception will be thrown because the iterator is invalid outside of this block and the behaviour is undefined
