A procedural macro for compiling GLSL into SPIR-V constants.
Unlike the standard
include_bytes macro, paths are currently
resolved relative to crate root. This is due to a temporary limitation
in the procedural macro API.
const VERT: &[u32] = include_glsl!("shaders/example.vert"); const FRAG: &[u32] = include_glsl!("shaders/example.glsl", kind: frag);
Debug info is generated by default; pass
strip to the macro to omit
it, or build the crate with the
strip feature enabled.
SPIR-V is a stream of 32-bit words, not bytes, and this is reflected
in APIs that consume it. In particular, passing a
[u8] of SPIR-V
that is not 4-byte-aligned to Vulkan is undefined behavior. Storing
SPIR-V in its native format guarantees that this will never occur,
without requiring copying or unsafe code.
This crate currently depends on the foreign
shaderc library. By default, it
will attempt to use an installed shaderc library. However if it does
not exist, it will fall back to building from source, requiring git,
cmake, python 3, and a supported C++ compiler to be available in the
build environment. When using a pre-compiled shaderc, care must be
taken to use a version that is binary-compatible with the one checked
out by the shaderc crate.
You can force shaderc to be built from source by enabling the
build-from-source feature on vk-shader-macros.
