Rust bindings for the shaderc library.

This is not an official Google product (experimental or otherwise), it is just code that happens to be owned by Google.

This library uses build.rs to automatically check out and compile a copy of native C++ shaderc and link to the generated artifacts, which requires git, cmake, and python existing in the PATH. To turn off this feature, specify --no-default-features when building. But then you will need to place a copy of the shaderc_combined library (on Windows) or the shaderc_shared library (on Linux and macOS) to a location that is scanned by the linker (e.g., the deps directory within the target directory).

First add to your Cargo.toml:

[dependencies]
shaderc = "0.3"

Then add to your crate root:

extern crate shaderc;

shaderc provides the Compiler interface to compile GLSL/HLSL source code into SPIR-V binary modules or assembly code. It can also assemble SPIR-V assembly into binary module. Default compilation behavior can be adjusted using CompileOptions. Successful results are kept in CompilationArtifacts.

Please see for detailed documentation.

Compile a shader into SPIR-V binary module and assembly text:

use shaderc;

let source = "#version 310 es\n void EP() {}";

let mut compiler = shaderc::Compiler::new().unwrap();
let mut options = shaderc::CompileOptions::new().unwrap();
options.add_macro_definition("EP", Some("main"));
let binary_result = compiler.compile_into_spirv(
    source, shaderc::ShaderKind::Vertex,
    "shader.glsl", "main", Some(&options)).unwrap();

assert_eq!(Some(&0x07230203), binary_result.as_binary().first());

let text_result = compiler.compile_into_spirv_assembly(
    source, shaderc::ShaderKind::Vertex,
    "shader.glsl", "main", Some(&options)).unwrap();

assert!(text_result.as_text().starts_with("; SPIR-V\n"));
