Struct CpuAccelerator 

pub struct CpuAccelerator { /* private fields */ }

Pure-CPU accelerator backed by rayon parallel iterators.

This implementation is always available and provides correct (if slower) results even when no GPU is present.

Implementations

impl CpuAccelerator

pub fn new() -> Self

Create a CPU accelerator using all available threads.

pub fn num_threads(&self) -> usize

Number of worker threads.

Trait Implementations

impl Default for CpuAccelerator

fn default() -> Self

Returns the “default value” for a type.
