Implementations§

source§

impl<'a> TypeSectionReader<'a>

source

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

Constructs a new TypeSectionReader for the given data and offset.

source

pub fn original_position(&self) -> usize

Gets the original position of the reader.

source

pub fn get_count(&self) -> u32

Gets a count of items in the section.

source

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

Reads content of the type section.

Examples
use wasmparser::TypeSectionReader;
let data: &[u8] = &[0x01, 0x60, 0x00, 0x00];
let mut reader = TypeSectionReader::new(data, 0).unwrap();
for _ in 0..reader.get_count() {
    let ty = reader.read().expect("type");
    println!("Type {:?}", ty);
}
