Module backend 

CPU execution and the interfaces used by future resident-buffer backends. Execution backends and resident-buffer abstractions.

crate::backend::CpuBackend is the implemented backend. Backend authors implement crate::backend::Backend and, when buffers can remain outside ordinary host arrays, crate::backend::ResidentBackend. Reconstruction code accesses these interfaces through crate::reconstruction::ReconstructionState.

Structs

BackendCapabilities

Feature declaration returned by an execution backend.

CpuBackend

rustfft-based CPU backend with plans cached for low- and high-resolution grids.

Enums

FftDirection

Direction of an unnormalized two-dimensional complex FFT.

MemoryLocation

Memory domain in which a backend buffer resides.

Traits

Backend

Minimal backend boundary. Buffers stay owned by reconstruction state.

ComplexBuffer

Type-erased contiguous buffer of Complex64 values owned by a resident backend.

RealBuffer

Type-erased contiguous buffer of f64 values owned by a resident backend.

ResidentBackend

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