Trait VectorSource 

pub trait VectorSource<F>: Sync {
    // Required methods
    fn len(&self) -> usize;
    fn is_empty(&self) -> bool;
    fn get_at(&self, index: usize) -> F;

    // Provided methods
    fn get_batch<const N: usize>(&self, indices: &[usize; N]) -> [F; N] { ... }
    fn prefetch(&self, _indices: &[usize]) { ... }
}

Abstract source of a vector for Matrix-Vector multiplication. Allows using both dense slices (RAM) and algorithmic generators (JIT).

Required Methods

fn len(&self) -> usize

Get the length of the virtual vector.

fn is_empty(&self) -> bool

fn get_at(&self, index: usize) -> F

Get the element at the specified index.

Provided Methods

fn get_batch<const N: usize>(&self, indices: &[usize; N]) -> [F; N]

Optimized batch fetch. Allows the source to use pipelining.

fn prefetch(&self, _indices: &[usize])

Software prefetching hook.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".

impl<F: Copy + Sync> VectorSource<F> for [F]

fn prefetch(&self, indices: &[usize])

Explicit prefetching implementation using Inline ASM.
