Implementations§

Source§

impl IntervalIndex

Source

pub fn new(bounds: Vec<(f64, f64)>, group_ids: Vec<usize>) -> Option<Self>

建立按左端点排序的最大右端点树,输入必须是已经验证的有限区间。

Source

pub fn query(&self, index: usize) -> Vec<usize>

返回当前行右侧的相交行,按原始索引排序以保持并查集合并顺序。

Source

pub fn rows(&self, start: usize, count: usize, budget: usize) -> Vec<Vec<usize>>

批量查询有限行数;单个极密行可以超过预算,但不会缓存整个页面的行对。
