wain-syntax-binary is a crate to parse WebAssembly binary format files.
This crate is part of larger wain project.
[dependencies]
wain-syntax-binary = "0"Using wain_syntax_binary::parse() is the easiest way.
extern crate wain_syntax_binary;
use std::fs;
use wain_syntax_binary::parse;
let source = fs::read("foo.wasm").unwrap();
match parse(&source) {
Ok(tree) => { /* `tree` is `wain_ast::Root` value */ }
Err(err) => eprintln!("Error! {}", err),
}For the syntax tree structure parsed by this library, please see wain-ast crate.
Using Parser struct, it can parse part of Wasm binary.
extern crate wain_syntax_binary;
use std::fs;
use wain_syntax_binary::Parser;
use wain_ast::DataSegment;
let source = fs::read("data_segment_only.bin").unwrap();
// Parse only data segment
let data: DataSegment<'_> = Parser.parse().unwrap();Working examples can be seen at examples/api/ directory
