Struct IntervalSet

source
pub struct IntervalSet<I> {
    map: SmallVec<[(u32, u32); 2]>,
    domain: usize,
    _data: PhantomData<I>,
}
Expand description

Stores a set of intervals on the indices.

The elements in map are sorted and non-adjacent, which means the second value of the previous element is greater than the first value of the following element.
