Struct cranelift_wasm::wasmparser::TagSectionReader

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

A reader for the tags section of a WebAssembly module.

Implementations

impl<'a> TagSectionReader<'a>

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

Constructs a new TagSectionReader 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<TagType, BinaryReaderError>

Reads content of the tag section.

Examples

use wasmparser::TagSectionReader;
let mut reader = TagSectionReader::new(data, 0).unwrap();
for _ in 0..reader.get_count() {
    let ty = reader.read().expect("tag type");
    println!("Tag type: {:?}", ty);
}

Trait Implementations

impl<'a> Clone for TagSectionReader<'a>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> IntoIterator for TagSectionReader<'a>

type Item = Result<TagType, BinaryReaderError>

The type of the elements being iterated over.

type IntoIter = SectionIteratorLimited<TagSectionReader<'a>>

Which kind of iterator are we turning this into?

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

Creates an iterator from a value.

impl<'a> SectionReader for TagSectionReader<'a>

type Item = TagType

The item returned by the reader.

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

fn get_count(&self) -> u32

Gets the count of the items in the section.
