Struct AlignedBuffer 

pub struct AlignedBuffer<T> { /* private fields */ }

Aligned growable f64 buffer for design-matrix materialization.

Implementations

impl<T: Copy + Default> AlignedBuffer<T>

pub const fn new() -> Self

Empty buffer.

pub fn resize(&mut self, len: usize)

Ensure at least len elements (grows, never shrinks; fills with default).

pub fn as_slice(&self, len: usize) -> &[T]

Borrow as slice of logical length len (must have been resized).

Panics

When len > self.data.len().

pub fn as_mut_slice(&mut self, len: usize) -> &mut [T]

Mutable borrow of logical length len.

Panics

When len > self.data.len().

pub fn capacity(&self) -> usize

Underlying capacity in elements.

pub fn len(&self) -> usize

Current allocated length (may exceed logical use).

pub fn is_empty(&self) -> bool

Whether empty.

impl AlignedBuffer<f64>

pub fn prepare_mut(&mut self, len: usize) -> &mut [f64]

Ensure capacity then return mutable slice of length len.
