Trait Implementations

impl<'a> Clone for OperatorsReader<'a>

pub fn clone(&self) -> OperatorsReader<'a>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Examples

use wasmparser::{Operator, CodeSectionReader, Result};
let mut code_reader = CodeSectionReader::new(data, 0).unwrap();
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
    );
}

type Item = Result<Operator<'a>, BinaryReaderError>

The type of the elements being iterated over.

type IntoIter = OperatorsIterator<'a>

Which kind of iterator are we turning this into?
