Struct wasmparser::ComponentImportSectionReader

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

A reader for the import section of a WebAssembly component.

Implementations

impl<'a> ComponentImportSectionReader<'a>

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

Constructs a new ComponentImportSectionReader 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<ComponentImport<'a>>

Reads content of the import section.

Examples

use wasmparser::ComponentImportSectionReader;
let data: &[u8] = &[0x01, 0x01, 0x41, 0x01, 0x66, 0x00, 0x00];
let mut reader = ComponentImportSectionReader::new(data, 0).unwrap();
for _ in 0..reader.get_count() {
    let import = reader.read().expect("import");
    println!("Import: {:?}", import);
}
