Struct cranelift_wasm::wasmparser::ExportSectionReader

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

A reader for the export section of a WebAssembly module.

Implementations

impl<'a> ExportSectionReader<'a>

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

Constructs a new ExportSectionReader 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<Export<'a>, BinaryReaderError>

Reads content of the export section.

Examples

use wasmparser::ExportSectionReader;

let mut reader = ExportSectionReader::new(data, 0).unwrap();
for _ in 0..reader.get_count() {
    let export = reader.read().expect("export");
    println!("Export: {:?}", export);
}

Trait Implementations

impl<'a> Clone for ExportSectionReader<'a>

fn clone(&self) -> ExportSectionReader<'a>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> IntoIterator for ExportSectionReader<'a>

type Item = Result<Export<'a>, BinaryReaderError>

The type of the elements being iterated over.

type IntoIter = SectionIteratorLimited<ExportSectionReader<'a>>

Which kind of iterator are we turning this into?

fn into_iter(self) -> <ExportSectionReader<'a> as IntoIterator>::IntoIter

Creates an iterator from a value.

impl<'a> SectionReader for ExportSectionReader<'a>

type Item = Export<'a>

The item returned by the reader.

fn read(
    &mut self
) -> Result<<ExportSectionReader<'a> as SectionReader>::Item, BinaryReaderError>

Reads an item from the section.

fn eof(&self) -> bool

Determines if the reader is at end-of-section.

fn original_position(&self) -> usize

Gets the original position of the reader.

fn range(&self) -> Range<usize>

Gets the range of the reader.

fn ensure_end(&self) -> Result<(), BinaryReaderError>

Ensures the reader is at the end of the section.

impl<'a> SectionWithLimitedItems for ExportSectionReader<'a>

fn get_count(&self) -> u32
