Struct wasmparser::FunctionSectionReader

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

Implementations

impl<'a> FunctionSectionReader<'a>

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

pub fn original_position(&self) -> usize

pub fn get_count(&self) -> u32

pub fn read(&mut self) -> Result<u32>

Reads function type index from the function section.

Examples

use wasmparser::FunctionSectionReader;
let mut function_reader = FunctionSectionReader::new(data, 0).unwrap();
for _ in 0..function_reader.get_count() {
    let ty = function_reader.read().expect("function type index");
    println!("Function type index: {}", ty);
}
