Struct LaggedSampleWorkspace 

pub struct LaggedSampleWorkspace {
    pub row_indexes: Vec<usize>,
    pub values: Vec<f64>,
    /* private fields */
}

Caller-owned scratch for repeated LaggedSamplePlan::prepare calls.

Fields

row_indexes: Vec<usize>

Reused row-index buffer (length = n_effective).

values: Vec<f64>

Column-major gathered values (ncols * n).

Implementations

impl LaggedSampleWorkspace

pub fn prepare(&mut self, n: usize, ncols: usize)

Ensure capacity for n rows and ncols columns (grows, never shrinks).

pub const fn capacity_n(&self) -> usize

Peak row capacity retained.

pub const fn capacity_cols(&self) -> usize

Peak column capacity retained.
