Optional typed-buffer operations for backends that can keep reconstruction state resident in their preferred memory domain.

Required Methods

fn allocate_complex(&self, len: usize) -> Result<Box<dyn ComplexBuffer>>

Allocates len uninitialized or zeroed complex elements according to backend policy.

fn allocate_real(&self, len: usize) -> Result<Box<dyn RealBuffer>>

Allocates len uninitialized or zeroed real elements according to backend policy.

fn upload_complex( &self, destination: &mut dyn ComplexBuffer, source: &[Complex64], ) -> Result<()>

Copies a host complex slice into an equal-length resident buffer.

fn download_complex( &self, source: &dyn ComplexBuffer, destination: &mut [Complex64], ) -> Result<()>

Copies an equal-length resident complex buffer into a host slice.

fn upload_real( &self, destination: &mut dyn RealBuffer, source: &[f64], ) -> Result<()>

Copies a host real slice into an equal-length resident buffer.

fn download_real( &self, source: &dyn RealBuffer, destination: &mut [f64], ) -> Result<()>

Copies an equal-length resident real buffer into a host slice.

fn fft2_resident( &self, values: &mut dyn ComplexBuffer, shape: (usize, usize), direction: FftDirection, ) -> Result<()>

Applies an in-place two-dimensional FFT to values shaped (height, width).
