impl IntSpan

INTERFACE: Inter-set OPs

pub fn overlap(&self, other: &Self) -> i32

overlap

Returns the size of intersection of two sets.

set.overlap(&other) equivalent to set.intersect(&other).cardinality()

let set = IntSpan::from("1");
let other = IntSpan::from("1");
assert_eq!(set.overlap(&other), 1);
let other = IntSpan::from("2");
assert_eq!(set.overlap(&other), 0);
let set = IntSpan::from("1-5");
let other = IntSpan::from("1-10");
assert_eq!(set.overlap(&other), 5);
let set = IntSpan::from("1-5,6");
let other = IntSpan::from("6-10");
assert_eq!(set.overlap(&other), 1);

pub fn distance(&self, other: &Self) -> i32

Returns the distance between sets, measured as follows.

• If the sets overlap, then the distance is negative and given by - set.overlap(&other)

• If the sets do not overlap, $d is positive and given by the distance on the integer line between the two closest islands of the sets.

let set = IntSpan::from("1");
let other = IntSpan::from("1");
assert_eq!(set.distance(&other), -1);
let other = IntSpan::from("");
assert_eq!(set.distance(&other), 0);
let other = IntSpan::from("2");
assert_eq!(set.distance(&other), 1);

let set = IntSpan::from("1-5");
let other = IntSpan::from("1-10");
assert_eq!(set.distance(&other), -5);
let other = IntSpan::from("10-15");
assert_eq!(set.distance(&other), 5);
let set = IntSpan::from("1-5,6");
let other = IntSpan::from("6-10");
assert_eq!(set.distance(&other), -1);

let set = IntSpan::from("1-5,10-15");
let other = IntSpan::from("5-9");
assert_eq!(set.distance(&other), -1);
let other = IntSpan::from("6");
assert_eq!(set.distance(&other), 1);
let other = IntSpan::from("7");
assert_eq!(set.distance(&other), 2);
let other = IntSpan::from("7-9");
assert_eq!(set.distance(&other), 1);
let other = IntSpan::from("16-20");
assert_eq!(set.distance(&other), 1);
let other = IntSpan::from("17-20");
assert_eq!(set.distance(&other), 2);
