Methods

impl<'a> OperatorsReader<'a>

pub fn eof(&self) -> bool

pub fn original_position(&self) -> usize

pub fn ensure_end(&self) -> Result<()>

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

pub fn into_iter_with_offsets<'b>(self) -> OperatorsIteratorWithOffsets<'b> where
    'a: 'b,

    'a: 'b, 

Trait Implementations

impl<'a> IntoIterator for OperatorsReader<'a>

type Item = Result<Operator<'a>>

The type of the elements being iterated over.

type IntoIter = OperatorsIterator<'a>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Reads content of the code section.

Examples

use wasmparser::{ModuleReader, Result, Operator};
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("code section");
let mut code_reader = section.get_code_section_reader().expect("code section reader");
for _ in 0..code_reader.get_count() {
    let body = code_reader.read().expect("function body");
    let mut op_reader = body.get_operators_reader().expect("op reader");
    let ops = op_reader.into_iter().collect::<Result<Vec<Operator>>>().expect("ops");
    assert!(
        if let [Operator::Nop, Operator::End] = ops.as_slice() { true } else { false },
        "found {:?}",
        ops
    );
