Struct ColumnarMatrix 

pub struct ColumnarMatrix {
    pub data: Vec<Vec<f64>>,
    pub timestamps: Vec<i64>,
    pub series_ids: Vec<String>,
}

Column-major matrix for aligned multi-series data.

Layout: data[series_idx][time_idx] — each inner Vec is one series.

Fields

data: Vec<Vec<f64>>

One row per series, contiguous for SIMD-friendly access.

timestamps: Vec<i64>

Common aligned timestamps.

series_ids: Vec<String>

Series identifiers (measurement + tags).

Implementations

impl ColumnarMatrix

pub fn n_series(&self) -> usize

Number of series (columns in the conceptual layout).

pub fn n_timestamps(&self) -> usize

Number of time points.

pub fn series(&self, idx: usize) -> Option<&[f64]>

Get a single series by index.

pub fn series_by_name(&self, name: &str) -> Option<&[f64]>

Get a single series by name.
