Struct Exception 

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

A WebAssembly exception instance.

An exception is an internal construct in WebAssembly that represents a runtime object that can be thrown. A WebAssembly exception consists of an exception tag and its runtime arguments.

Spec: https://github.com/WebAssembly/exception-handling/blob/main/proposals/exception-handling/Exceptions.md#exceptions

Implementations

impl Exception

pub fn new(store: &mut impl AsStoreMut, tag: &Tag, payload: &[Value]) -> Self

Create a new exception with the given tag and payload, and also creates a reference to it, returning the reference.

pub fn is_from_store(&self, store: &impl AsStoreRef) -> bool

Check whether this Exception comes from the given store.

pub fn tag(&self, store: &impl AsStoreRef) -> Tag

Get the exception tag.

pub fn payload(&self, store: &mut impl AsStoreMut) -> Vec<Value>

Get the exception payload values.

pub fn vm_exceptionref(&self) -> VMExceptionRef

Get the VMExceptionRef corresponding to this Exception.

pub fn from_vm_exceptionref(exnref: VMExceptionRef) -> Self

Create an Exception from a VMExceptionRef.

Trait Implementations

impl Clone for Exception

fn clone(&self) -> Exception

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Exception

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

Formats the value using the given formatter.

impl From<Exception> for Value

fn from(val: Exception) -> Self

Converts to this type from the input type.

impl PartialEq for Exception

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