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