Struct wasmparser::AliasSectionReader

pub struct AliasSectionReader<'a> { /* private fields */ }

A reader for the core alias section of a WebAssembly component.

Implementations

impl<'a> AliasSectionReader<'a>

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

Constructs a new AliasSectionReader for the given data and offset.

pub fn original_position(&self) -> usize

Gets the original position of the section reader.

pub fn get_count(&self) -> u32

Gets the count of items in the section.

pub fn read(&mut self) -> Result<Alias<'a>>

Reads content of the core alias section.

Examples

use wasmparser::AliasSectionReader;
let data: &[u8] = &[0x01, 0x00, 0x00, 0x00, 0x03, b'f', b'o', b'o'];
let mut reader = AliasSectionReader::new(data, 0).unwrap();
for _ in 0..reader.get_count() {
    let alias = reader.read().expect("alias");
    println!("Alias: {:?}", alias);
}
