#![doc(html_root_url = "https://docs.rs/rspirv/0.7/")] //! Library APIs for SPIR-V module processing functionalities. //! //! This library provides: //! //! * The whole SPIR-V [grammar](grammar/index.html) (instruction layouts //! and their operands) //! * A [data representation](dr/index.html) of SPIR-V modules and its //! loader and builder //! * A [structured representation](sr/index.html) of SPIR-V modules //! (under developing) //! * SPIR-V [binary](binary/index.html) module decoding and parsing //! functionalities //! //! The data representation (DR) focuses on presenting the data within a //! SPIR-V module; it uses plain vectors to hold data of SPIR-V instructions, //! following the instructions' layouts defined in the grammar. DR has little //! structure; only bare structures need for representing modules, functions, //! and blocks are adopted. //! //! The structured representation (SR) focuses on presenting the structure //! within a SPIR-V module; it tries to links as much information as possible. //! Types, values, instructions, decorations and so on have their dedicated //! structs. The purpose of SR is to facilitate SPIR-V analysis and //! transformations. //! //! # Examples //! //! Building a SPIR-V module, assembling it, parsing it, and then //! disassembling it: //! //! ``` //! extern crate rspirv; //! extern crate spirv_headers as spirv; //! //! use rspirv::binary::Assemble; //! use rspirv::binary::Disassemble; //! //! fn main() { //! // Building //! let mut b = rspirv::dr::Builder::new(); //! b.memory_model(spirv::AddressingModel::Logical, spirv::MemoryModel::GLSL450); //! let void = b.type_void(); //! let voidf = b.type_function(void, vec![void]); //! b.begin_function(void, //! None, //! (spirv::FunctionControl::DONT_INLINE | //! spirv::FunctionControl::CONST), //! voidf) //! .unwrap(); //! b.begin_block(None).unwrap(); //! b.ret().unwrap(); //! b.end_function().unwrap(); //! let module = b.module(); //! //! // Assembling //! let code = module.assemble(); //! assert!(code.len() > 20); // Module header contains 5 words //! assert_eq!(spirv::MAGIC_NUMBER, code[0]); //! //! // Parsing //! let mut loader = rspirv::dr::Loader::new(); //! rspirv::binary::parse_words(&code, &mut loader).unwrap(); //! let module = loader.module(); //! //! // Disassembling //! assert_eq!(module.disassemble(), //!
