}

Trait defining retry signatures

Required methods

Important traits for MapIter<Iter, F>

impl<Iter: Iterator, F: FnMut(Iter::Item) -> Result<Out, E>, Out, E> Iterator for MapIter<Iter, F> where
    Iter::Item: Clone,  type Item = Result<Out, E>;

fn map_retry<F>(self, f: F) -> MapIter<Self, F>

Works the same as map function, but retries failures. Return type of provided closure must of type Result if result is error iterator retries to apply function agian.

Order of elements is not guaranteed. All elements in original iterator are returned.

Important traits for MapIter<Iter, F>

impl<Iter: Iterator, F: FnMut(Iter::Item) -> Result<Out, E>, Out, E> Iterator for MapIter<Iter, F> where
    Iter::Item: Clone,  type Item = Result<Out, E>;

fn map_retry<F>(self, f: F) -> MapIter<Self, F>

Runs map function which retries results that return error.

Errors are retried only after all elements have been mapped. Maping function must return Result type. Items are cloned when error is returned.
