[−][src]Crate spans
This crate allows you to split an iterator into contiguous spans.
Import the Spans
trait to extend Iterator
:
use spans::Spans;
Now you can use spans_by_key
to split an iterator into contiguous spans:
let vec = vec![1, 2, 5, 6, 7, 11, 13, 14, 15]; let mut spans = vec.iter().spans_by_key(|&&x| x, |a, b| a + 1 == b); while let Some(span) = spans.next() { println!("span = {:?}", span.collect::<Vec<_>>()); }
The code above splits the vector into spans where each item is 1 larger than the proceeding item. The following text is printed:
span = [1, 2]
span = [5, 6, 7]
span = [11]
span = [13, 14, 15]
For more information, refer to the spans_by_key
documentation.
