Expand description
A reader for the component instance section of a WebAssembly component.
Implementations
sourceimpl<'a> ComponentInstanceSectionReader<'a>
impl<'a> ComponentInstanceSectionReader<'a>
sourcepub fn new(
data: &'a [u8],
offset: usize
) -> Result<ComponentInstanceSectionReader<'a>, BinaryReaderError>
pub fn new(
data: &'a [u8],
offset: usize
) -> Result<ComponentInstanceSectionReader<'a>, BinaryReaderError>
Constructs a new ComponentInstanceSectionReader
for the given data and offset.
sourcepub fn original_position(&self) -> usize
pub fn original_position(&self) -> usize
Gets the original position of the section reader.
sourcepub fn read(&mut self) -> Result<ComponentInstance<'a>, BinaryReaderError>
pub fn read(&mut self) -> Result<ComponentInstance<'a>, BinaryReaderError>
Reads content of the instance section.
Examples
use wasmparser::ComponentInstanceSectionReader;
let mut reader = ComponentInstanceSectionReader::new(data, 0).unwrap();
for _ in 0..reader.get_count() {
let instance = reader.read().expect("instance");
println!("Instance: {:?}", instance);
}
