Struct wasmparser::CodeSectionReader

pub struct CodeSectionReader<'a> { /* fields omitted */ }

Methods

impl<'a> CodeSectionReader<'a>

pub fn new(data: &'a [u8], offset: usize) -> Result<CodeSectionReader<'a>>

pub fn original_position(&self) -> usize

pub fn get_count(&self) -> u32

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

Reads content of the code section.

Examples

use wasmparser::ModuleReader;
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 binary_reader = body.get_binary_reader();
    assert!(binary_reader.read_local_count().expect("local count") == 0);
    let op = binary_reader.read_operator().expect("first operator");
    println!("First operator: {:?}", op);
}
