Struct wasmtime_environ::wasmparser::TableSectionReader

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

A reader for the table section of a WebAssembly module.

Implementations

impl<'a> TableSectionReader<'a>

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

Constructs a new TableSectionReader 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<TableType, BinaryReaderError>

Reads content of the table section.

Examples

use wasmparser::TableSectionReader;

let mut table_reader = TableSectionReader::new(data, 0).unwrap();
for _ in 0..table_reader.get_count() {
    let table = table_reader.read().expect("table");
    println!("Table: {:?}", table);
}

Trait Implementations

impl<'a> Clone for TableSectionReader<'a>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> IntoIterator for TableSectionReader<'a>

type Item = Result<TableType, BinaryReaderError>

The type of the elements being iterated over.

type IntoIter = SectionIteratorLimited<TableSectionReader<'a>>

Which kind of iterator are we turning this into?

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

Creates an iterator from a value.

impl<'a> SectionReader for TableSectionReader<'a>

type Item = TableType

The item returned by the reader.

fn read(
    &mut self
) -> Result<<TableSectionReader<'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 TableSectionReader<'a>

fn get_count(&self) -> u32

Gets the count of the items in the section.
