Crate fallible_streaming_iterator

Fallible, streaming iteration.

FallibleStreamingIterator differs from the standard library’s Iterator trait in two ways: iteration can fail, resulting in an error, and only one element of the iteration is available at any time.

While these iterators cannot be used with Rust for loops, while let loops offer a similar level of ergonomics:

while let Some(value) = it.next()? {
    // use value
}
