Struct wasmparser::RefType

#[repr(packed(1))]
pub struct RefType {
    pub nullable: bool,
    pub heap_type: HeapType,
}

A reference type. When the function references feature is disabled, this only represents funcref and externref, using the following format: RefType { nullable: true, heap_type: Func | Extern })

Fields

nullable: bool

Whether it’s nullable

heap_type: HeapType

The relevant heap type

Implementations

impl RefType

pub const FUNCREF: RefType = _

Alias for the wasm funcref type.

pub const EXTERNREF: RefType = _

Alias for the wasm externref type.

Trait Implementations

impl Clone for RefType

fn clone(&self) -> RefType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RefType

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

Formats the value using the given formatter.

impl From<RefType> for ValType

fn from(ty: RefType) -> ValType

Converts to this type from the input type.

impl<'a> FromReader<'a> for RefType

fn from_reader(reader: &mut BinaryReader<'a>) -> Result<Self>

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

impl Hash for RefType

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for RefType

fn eq(&self, other: &RefType) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
