Slang Rust Bindings

Rust bindings for the Slang shader language compiler. In contrast to existing bindings, these internally use Slang's COM/C++ API because the old C API is soon to be deprecated.

Currently mostly reflects the needs of our own engine but issues and pull requests are more than welcome.

Example

let session = slang::GlobalSession::new();

let mut compile_request = session.create_compile_request();

compile_request
	.set_codegen_target(slang::CompileTarget::Dxil)
	.set_target_profile(session.find_profile("sm_6_5"));

let entry_point = compile_request
	.add_translation_unit(slang::SourceLanguage::Slang, None)
	.add_source_file(filepath)
	.add_entry_point("main", slang::Stage::Compute);

let shader_bytecode = compile_request
	.compile()
	.expect("Shader compilation failed.")
	.get_entry_point_code(entry_point);

Installation

Add the following to the [dependencies] section of your Cargo.toml:

slang = { git = "https://github.com/FloatyMonkey/slang-rs.git" }

Set the SLANG_DIR environment variable to the path of your Slang installation. Download the latest release from their releases page. Copy slang.dll to your executable's directory.

To compile to DXIL bytecode you need the Microsoft DirectXShaderCompiler. Download the latest release from their releases page. Copy dxil.dll and dxcompiler.dll to your executable's directory.
