Trait SparseBackend 

pub trait SparseBackend {
    // Required methods
    fn spmv_kernel(
        a: &CsrMatrix<f32>,
        alpha: f32,
        x: &[f32],
        beta: f32,
        y: &mut [f32],
    );
    fn spmm_kernel(
        a: &CsrMatrix<f32>,
        alpha: f32,
        b: &[f32],

        beta: f32,
        c: &mut [f32],
    );
}

Backend dispatch trait for pluggable SIMD SpMV kernels.

Implementations provide SpMV for a specific hardware target. The default dispatch in SparseOps::spmv selects the best available backend at runtime.

Required Methods

fn spmv_kernel( a: &CsrMatrix<f32>, alpha: f32, x: &[f32], beta: f32, y: &mut [f32], )

Perform SpMV: y = alpha * A * x + beta * y using this backend.

fn spmm_kernel( a: &CsrMatrix<f32>, alpha: f32, b: &[f32], b_cols: usize, beta: f32, c: &mut [f32], )

Perform SpMM: C = alpha * A * B + beta * C using this backend.

B is row-major with b_cols columns.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
