pub struct BufferedDesign<'a, M: ?Sized>

A borrowed design with one caller-owned block buffer for sequential scans.

Raw products use packed blocks; lazymatrix::LazyMatrix applies training normalization. Statistics retain the backend's combined scan hook. The adapter does not provide borrowed columns or rows, cache chunks, or require a full-width row buffer. Product outputs may be partial after an error.

The buffer remains borrowed until this adapter is dropped. Internal mutable borrowing supports the shared-reference operator traits; this adapter is intended for synchronous use and is not Sync. The design must remain unchanged across validation, normalization, and fitting.

Inherent implementation

impl<'a, M: ReadBlock<f64> + ?Sized> BufferedDesign<'a, M>

`new`

Source: src/experimental.rs

pub fn new(
    matrix: &'a M,
    block_shape: [usize; 2],
    buffer: &'a mut [f64]
) -> Self

Borrow a design and initialized buffer for blocks of at most block_shape.

Storage chunk and codec workspace can exceed the caller's buffer size.

Panics

Panics for a zero block dimension, dimension overflow, or a buffer shorter than the product of the requested block dimensions.
