Struct wasmparser::BinaryReader

pub struct BinaryReader<'a> { /* fields omitted */ }

A binary reader of the WebAssembly structures and types.

Methods

impl<'a> BinaryReader<'a>

fn new(data: &[u8]) -> BinaryReader

Constructs BinaryReader type.

Examples

let fn_body = &vec![0x41, 0x00, 0x10, 0x00, 0x0B];
let mut reader = wasmparser::BinaryReader::new(fn_body);
while !reader.eof() {
    let op = reader.read_operator();
    println!("{:?}", op)
}
