Implementations
sourceimpl<'a> ElementSectionReader<'a>
impl<'a> ElementSectionReader<'a>
sourcepub fn new(data: &'a [u8], offset: usize) -> Result<ElementSectionReader<'a>>
pub fn new(data: &'a [u8], offset: usize) -> Result<ElementSectionReader<'a>>
Constructs a new ElementSectionReader
for the given data and offset.
sourcepub fn original_position(&self) -> usize
pub fn original_position(&self) -> usize
Gets the original position of the section reader.
sourcepub fn read<'b>(&mut self) -> Result<Element<'b>> where
'a: 'b,
pub fn read<'b>(&mut self) -> Result<Element<'b>> 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 { offset_expr, .. } = element.kind {
let mut offset_expr_reader = offset_expr.get_binary_reader();
let op = offset_expr_reader.read_operator().expect("op");
println!("offset expression: {:?}", 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);
}
}
