rust-lapper

Documentation

Crates.io

This is a rust port of Brent Pendersen's nim-lapper. It has a few notable differences, mostly that the find and seek methods both return iterators, so all adaptor methods may be used normally.

Example

```rust use rust_lapper::{Interval, Lapper}; use std::cmp;

type Iv = Interval; fn main() { // create some fake data let data: Vec = (0..20).step_by(5).map(|x| Iv{start: x, stop: x + 2, val: 0}).collect(); println!("{:#?}", data);

// make lapper structure
let laps = Lapper::new(data);

assert_eq!(laps.find(6, 11).next(), Some(&Iv{start: 5, stop: 7, val: 0}));

let mut sim: i32 = 0;
let mut cursor = 0;
// Calculate the overlap between the query and the found intervals, sum total overlap
for i in (0..10).step_by(3) {
    sim += laps
        .seek(i, i + 2, &mut cursor)
        .map(|iv| cmp::min(i + 2, iv.stop) - cmp::max(i, iv.start))
        .sum::<i32>();
}
assert_eq!(sim, 10);

} ```
