pub struct OperatorsReader<'a> { /* private fields */ }
Expand description

A reader for a core WebAssembly function’s operators.

Implementations

Determines if the reader is at the end of the operators.

Gets the original position of the reader.

Whether or not to allow 64-bit memory arguments in the the operators being read.

This is intended to be true when support for the memory64 WebAssembly proposal is also enabled.

Ensures the reader is at the end.

This function returns an error if there is extra data after the operators.

Reads an operator from the reader.

Converts to an iterator of operators paired with offsets.

Reads an operator with its offset.

Visits an operator with its offset.

Gets a binary reader from this operators reader.

Reads content of the code section.

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
    );
}

The type of the elements being iterated over.
