Function ranges_difference

pub fn ranges_difference<F>(
    from: &[RawRange],
    exclude: &[RawRange],
    result_op: F,
) -> Result<(), OverlapErr>
where
    F: FnMut(RawRange),

Removes a portion of ranges from the given ranges.

from is a list of ranges to be operated on, and exclude is a list of ranges to be removed. exclude should have been sorted by the start, and have non-overlapping ranges. If not, an error will be returned.

The result is also a list of ranges with each range contained in from but not in exclude. result_op is a closure that will be called for each range in the result.

Example

let mut res = Vec::new();
// 0..10, 20..30 - 5..15, 15..25 = 0..5, 25..30
ranges_difference(&[(0, 10), (20, 10)], &[(5, 10), (15, 10)], |r| res.push(r)).unwrap();
assert_eq!(res, &[(0, 5), (25, 5)]);
