Implementations

impl<'a> ElementSectionReader<'a>

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

pub fn original_position(&self) -> usize

pub fn get_count(&self) -> u32

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

Reads content of the element section.

Examples

use wasmparser::{ElementSectionReader, ElementKind};
let mut element_reader = ElementSectionReader::new(data, 0).unwrap();
for _ in 0..element_reader.get_count() {
    let element = element_reader.read().expect("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);
    }
}

Trait Implementations
