Struct wasmparser::DataSectionReader

pub struct DataSectionReader<'a> { /* private fields */ }

Implementations

impl<'a> DataSectionReader<'a>

pub fn new(data: &'a [u8], offset: usize) -> Result<DataSectionReader<'a>>

pub fn original_position(&self) -> usize

pub fn get_count(&self) -> u32

pub fn read<'b>(&mut self) -> Result<Data<'b>>where
    'a: 'b,

Reads content of the data section.

Examples

use wasmparser::ModuleReader;
let mut reader = ModuleReader::new(data).expect("module reader");
let section = reader.read().expect("type section");
let section = reader.read().expect("function section");
let section = reader.read().expect("memory section");
let section = reader.read().expect("code section");
let section = reader.read().expect("data section");
let mut data_reader = section.get_data_section_reader().expect("data section reader");
for _ in 0..data_reader.get_count() {
    let data = data_reader.read().expect("data");
    println!("Data: {:?}", data);
    let mut init_expr_reader = data.init_expr.get_binary_reader();
    let op = init_expr_reader.read_operator().expect("op");
    println!("Init const: {:?}", op);
}
