Expand description
A reader for the type section of a WebAssembly module.
Implementations
sourceimpl<'a> TypeSectionReader<'a>
impl<'a> TypeSectionReader<'a>
sourcepub fn new(
data: &'a [u8],
offset: usize
) -> Result<TypeSectionReader<'a>, BinaryReaderError>
pub fn new(
data: &'a [u8],
offset: usize
) -> Result<TypeSectionReader<'a>, BinaryReaderError>
Constructs a new TypeSectionReader
for the given data and offset.
sourcepub fn original_position(&self) -> usize
pub fn original_position(&self) -> usize
Gets the original position of the reader.
sourcepub fn read(&mut self) -> Result<Type, BinaryReaderError>
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);
}
