Implementations

impl Exception

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

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

pub fn exnref(&self) -> VMExceptionRef

pub fn from_exnref(exnref: VMExceptionRef) -> Self

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

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

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

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 BackendException

fn from(value: 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.
