gpufft-vulkan-sys

Raw FFI bindings to VkFFT, vendored and built from source at crate-build time. This is internal plumbing for gpufft; you almost certainly want that crate, not this one.

crates.io docs.rs License: Apache-2.0

What this crate is

  • Vendored copy of VkFFT v1.3.4 (header-only C++, MIT-licensed) under vendor/VkFFT/.
  • A small C shim (vkfft_shim.c) that exposes a C ABI to Rust.
  • bindgen-generated bindings for that shim.
  • A cc build step that compiles the shim + VkFFT.

What this crate is not

  • A safe Rust API. All symbols are unsafe. Use gpufft for the typed trait surface.
  • A Vulkan loader. This crate expects Vulkan headers and loader to be available at build time; it does not vendor the Vulkan SDK.

Build prerequisites

  • Vulkan headers + loader: vulkan-headers, vulkan-loader-devel (Fedora) or the LunarG Vulkan SDK (Ubuntu/Debian/macOS).
  • glslang + SPIRV-Tools development packages for VkFFT's SPIR-V emission path.
  • A C++17-capable compiler (invoked via cc).

pkg-config is used to locate Vulkan. If pkg-config fails, set VULKAN_SDK to a directory containing include/vulkan/ and a loader library.

Licensing

gpufft-vulkan-sys itself is Apache-2.0. The vendored VkFFT sources are MIT-licensed; see vendor/VkFFT/LICENSE in the packaged crate and the project NOTICE file in the repository.
