pub struct Exception(pub(crate) BackendException);Expand description
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.

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

Sourcepub fn is_from_store(&self, store: &impl AsStoreRef) -> bool
pub fn is_from_store(&self, store: &impl AsStoreRef) -> bool
Check whether this Exception comes from the given store.
Sourcepub fn tag(&self, store: &impl AsStoreRef) -> Tag
pub fn tag(&self, store: &impl AsStoreRef) -> Tag
Get the exception tag.
Sourcepub fn payload(&self, store: &mut impl AsStoreMut) -> Vec<Value>
pub fn payload(&self, store: &mut impl AsStoreMut) -> Vec<Value>
Get the exception payload values.
Sourcepub fn vm_exceptionref(&self) -> VMExceptionRef
pub fn vm_exceptionref(&self) -> VMExceptionRef
Get the VMExceptionRef corresponding to this Exception.
Sourcepub fn from_vm_exceptionref(exnref: VMExceptionRef) -> Self
pub fn from_vm_exceptionref(exnref: VMExceptionRef) -> Self
Create an Exception from a VMExceptionRef.
