Struct ExternRef

pub struct ExternRef { /* private fields */ }

An opaque reference to some data. This reference can be passed through Wasm.

Implementations

impl ExternRef

pub fn is_null(&self) -> bool

Checks if the given ExternRef is null.

pub fn null() -> Self

New null extern ref

Trait Implementations

impl Clone for ExternRef

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ExternRef

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

Formats the value using the given formatter.

impl Drop for ExternRef

fn drop(&mut self)

Executes the destructor for this type.

impl From<ExternRef> for VMExternRef

fn from(other: ExternRef) -> Self

Converts to this type from the input type.

impl<T> From<ExternRef> for Value<T>

where T: WasmValueType,

fn from(val: ExternRef) -> Self

Converts to this type from the input type.

impl From<VMExternRef> for ExternRef

fn from(other: VMExternRef) -> Self

Converts to this type from the input type.

impl PartialEq for ExternRef

fn eq(&self, other: &ExternRef) -> 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.
