Implementations§

Source§

impl Columns

Source

pub fn new(compensated: bool) -> Self

首个锚点的均值保持原值;累计器模拟 Python 整数零加首个浮点值。

Source

pub fn extend( &mut self, rows: &[Vec<(f64, f64)>], tolerance: f64, ) -> Option<(usize, f64)>

单调追加行并保持每簇去重后的行覆盖量,溢出后丢弃整个原生状态。

Source

pub fn extend_refs( &mut self, rows: &[&[(f64, f64)]], tolerance: f64, ) -> Option<(usize, f64)>

自有页面锚点通过借用片段追加,不再为每个区间复制嵌套数值数组。
