source · [−]pub struct InstanceSectionReader<'a> { /* private fields */ }
Expand description
A reader for the core instance section of a WebAssembly component.
Implementations
sourceimpl<'a> InstanceSectionReader<'a>
impl<'a> InstanceSectionReader<'a>
sourcepub fn new(data: &'a [u8], offset: usize) -> Result<Self>
pub fn new(data: &'a [u8], offset: usize) -> Result<Self>
Constructs a new InstanceSectionReader
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<Instance<'a>>
pub fn read(&mut self) -> Result<Instance<'a>>
Reads content of the instance section.
Examples
use wasmparser::InstanceSectionReader;
let mut reader = InstanceSectionReader::new(data, 0).unwrap();
for _ in 0..reader.get_count() {
let instance = reader.read().expect("instance");
println!("Instance: {:?}", instance);
}
