Struct wasmtime_environ::wasmparser::ComponentStartSectionReader

pub struct ComponentStartSectionReader<'a>(_);

A reader for the start section of a WebAssembly component.

Implementations

impl<'a> ComponentStartSectionReader<'a>

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

Constructs a new ComponentStartSectionReader for the given data and offset.

pub fn original_position(&self) -> usize

Gets the original position of the section reader.

pub fn read(&mut self) -> Result<ComponentStartFunction, BinaryReaderError>

Reads the start function from the section.

Examples

use wasmparser::ComponentStartSectionReader;

let mut reader = ComponentStartSectionReader::new(data, 0).unwrap();
let start = reader.read().expect("start");
println!("Start: {:?}", start);
