Struct wasmtime_environ::wasmparser::FunctionBody

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

Represents a WebAssembly function body.

Implementations

impl<'a> FunctionBody<'a>

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

Constructs a new FunctionBody for the given data and offset.

pub fn allow_memarg64(&mut self, allow: bool)

Whether or not to allow 64-bit memory arguments in the function body.

This is intended to be true when support for the memory64 WebAssembly proposal is also enabled.

pub fn get_binary_reader(&self) -> BinaryReader<'a>

Gets a binary reader for this function body.

pub fn get_locals_reader(&self) -> Result<LocalsReader<'a>, BinaryReaderError>

Gets the locals reader for this function body.

pub fn get_operators_reader( &self ) -> Result<OperatorsReader<'a>, BinaryReaderError>

Gets the operators reader for this function body.

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

Gets the range of the function body.

Trait Implementations

impl<'a> Clone for FunctionBody<'a>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for FunctionBody<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<'a> FromReader<'a> for FunctionBody<'a>

fn from_reader( reader: &mut BinaryReader<'a> ) -> Result<FunctionBody<'a>, BinaryReaderError>

Attempts to read Self from the provided binary reader, returning an error if it is unable to do so.
