Struct ExternRef 

pub struct ExternRef(/* private fields */);

Implementations

impl ExternRef

pub const fn new(addr: Option<ExternAddr>) -> Self

Create a new ExternRef from an ExternAddr. Should only be used by the runtime.

pub const fn null() -> Self

Create a null ExternRef.

pub const fn is_null(&self) -> bool

Check if the ExternRef is null.

pub const fn addr(&self) -> Option<ExternAddr>

Get the ExternAddr from the ExternRef.

Trait Implementations

impl Clone for ExternRef

fn clone(&self) -> ExternRef

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExternRef

Available on crate feature debug only.

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

Formats the value using the given formatter.

impl From<ExternRef> for WasmValue

fn from(i: ExternRef) -> 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.

impl TryFrom<WasmValue> for ExternRef

type Error = ()

The type returned in the event of a conversion error.

fn try_from(value: WasmValue) -> Result<Self, Self::Error>

Performs the conversion.
