Implementations
sourceimpl<'a> DataSectionReader<'a>
impl<'a> DataSectionReader<'a>
sourcepub fn new(
data: &'a [u8],
offset: usize
) -> Result<DataSectionReader<'a>, BinaryReaderError>
pub fn new(
data: &'a [u8],
offset: usize
) -> Result<DataSectionReader<'a>, BinaryReaderError>
Constructs a new DataSectionReader
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<Data<'b>, BinaryReaderError> where
'a: 'b,
pub fn read<'b>(&mut self) -> Result<Data<'b>, BinaryReaderError> where
'a: 'b,
Reads content of the data section.
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 { offset_expr, .. } = data.kind {
let mut offset_expr_reader = offset_expr.get_binary_reader();
let op = offset_expr_reader.read_operator().expect("op");
println!("offset expression: {:?}", op);
}
}
