spirv-reflect

Reflection API in rust for SPIR-V shader byte code, intended for Vulkan applications.

This crate provides an FFI layer and idiomatic rust wrappers for the excellent SPIRV-Reflect C/C++ library.

• Documentation
• Release Notes

Features

• Extract descriptor bindings from SPIR-V bytecode, to assist in the generation of Vulkan descriptor set and pipeline layouts.
• Extract push constant block size from SPIR-V bytecode to assist in the generation of pipeline layouts.
• Extract full layout data for uniform buffer and push constant blocks from SPIR-V bytecode, to assist in application updates of these structures.
• Extract input/output variables from SPIR-V bytecode (including semantic decorations for HLSL shaders), to assist in validation of pipeline input/output settings.
• Easily map Vulkan types to DirectX 12 resource types
• Remap descriptor bindings, and update the source SPIR-V bytecode accordingly.
• Log all reflection data as human-readable text.

Planned Features

• Extensive unit tests and examples.
• Pure rust version.
• Command line tool for reflection and manipulation.

Usage

Add this to your Cargo.toml:

[dependencies]
spirv-reflect = "0.2.3"

and add this to your crate root:

extern crate spirv_reflect;

Example

Currently there is only a single monolithic demo example, which shows some usage. A CLI tool is planned that will be useful on its own, and as a clean example of usage patterns.

cargo run --release --example demo
