Examples

use wasmparser::{DataSectionReader, DataKind};
let mut data_reader = DataSectionReader::new(data, 0).unwrap();
for _ in 0..data_reader.get_count() {
    let data = data_reader.read().expect("data");
    println!("Data: {:?}", data);
    if let DataKind::Active { init_expr, .. } = data.kind {
        let mut init_expr_reader = init_expr.get_binary_reader();
        let op = init_expr_reader.read_operator().expect("op");
        println!("Init const: {:?}", op);
