Using wain_syntax_binary::parse() is the easiest way.
```rust extern crate wainsyntaxbinary;
use std::fs; use wainsyntaxbinary::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.
```rust extern crate wainsyntaxbinary;
use std::fs; use wainsyntaxbinary::Parser; use wain_ast::DataSegment;
let source = fs::read("datasegmentonly.bin").unwrap();
// Parse only data segment let data: DataSegment<'_> = Parser.parse().unwrap(); ```
