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
}

Structs

• Convert
  An iterator which wraps a normal Iterator.
• Empty

  An iterator which filters elements with a predicate.
• Fuse
  An iterator which is well-behaved at the beginning and end of iteration.
• Map
  An iterator which applies a transform to elements.
• MapErr
  An iterator which applies a transform to errors.
• MapRef
  An iterator which applies a transform to elements.
• Skip
  An iterator which skips a number of initial elements.
• SkipWhile
  An iterator which skips initial elements matching a predicate.
• Take
  An iterator which only returns a number of initial elements.
• TakeWhile
  An iterator which only returns initial elements matching a predicate.
