Struct wasmparser::ElementSectionReader

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

Methods

impl<'a> ElementSectionReader<'a>

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

pub fn original_position(&self) -> usize

pub fn get_count(&self) -> u32

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

Reads content of the element section.

Examples

use wasmparser::{ModuleReader, ElementKind};
use wasmparser::Result;
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("table section");
let section = reader.read().expect("element section");
let mut element_reader = section.get_element_section_reader().expect("element section reader");
for _ in 0..element_reader.get_count() {
    let element = element_reader.read().expect("element");
    println!("Element: {:?}", element);
    if let ElementKind::Active { init_expr, .. } = element.kind {
        let mut init_expr_reader = init_expr.get_binary_reader();
        let op = init_expr_reader.read_operator().expect("op");
        println!("Init const: {:?}", op);
    }
    let mut items_reader = element.items.get_items_reader().expect("items reader");
    for _ in 0..items_reader.get_count() {
        let item = items_reader.read().expect("item");
        println!("  Item: {}", item);
    }
}
