Implementations

impl Ref

pub fn null(type_: RefType) -> Self

Returns a null Ref of the given RefType.

pub fn type_(self) -> RefType

Returns the RefType of this Ref.

pub fn is_func_ref(self) -> bool

Returns true if this Ref is a FuncRef.

pub fn is_extern_ref(self) -> bool

Returns true if this Ref is an ExternRef.

pub fn to_func_ref(self) -> Option<FuncRef>

Converts this Ref to a FuncRef, if it is one.

pub fn to_extern_ref(self) -> Option<ExternRef>

Converts this Ref to an ExternRef, if it is one.

Trait Implementations

impl Clone for Ref

fn clone(&self) -> Ref

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Ref

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

Formats the value using the given formatter.

impl From<ExternRef> for Ref

fn from(val: ExternRef) -> Self

Converts to this type from the input type.

impl From<FuncRef> for Ref

fn from(val: FuncRef) -> Self

Converts to this type from the input type.

impl From<Ref> for Val

fn from(val: Ref) -> Self

Converts to this type from the input type.

impl Hash for Ref

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 Ref

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl Copy for Ref

impl Eq for Ref

impl StructuralPartialEq for Ref
