Struct rspirv::binary::Parser
[−]
[src]
pub struct Parser<'c, 'd> { /* fields omitted */ }
The SPIR-V binary parser.
Takes in a vector of bytes and a consumer, this parser will invoke the consume methods on the consumer for the module header and each instruction parsed.
Different from the Decoder
,
this parser is high-level; it has knowlege of the SPIR-V grammar.
It will parse instructions according to SPIR-V grammar.
Examples
extern crate rspirv; extern crate spirv_headers as spirv; use spirv::{AddressingModel, MemoryModel}; use rspirv::binary::Parser; use rspirv::mr::{Loader, Operand}; fn main() { let bin = vec![ // Magic number.
