Enum EngineError 

pub enum EngineError {
    NoInstructionsRemain,
    RuntimeLimit(RuntimeLimitError),
    Panic(PanicError),
}

Engine error that cannot be caught from within ECMAScript code.

Variants

NoInstructionsRemain

Error thrown when no instructions remain. Only used in a fuzzing context.

RuntimeLimit(RuntimeLimitError)

Error thrown when a runtime limit is exceeded.

Panic(PanicError)

Error thrown when an internal panic condition is encountered.

Trait Implementations

impl Clone for EngineError

fn clone(&self) -> EngineError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EngineError

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

Formats the value using the given formatter.

impl Display for EngineError

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

Formats the value using the given formatter.

impl Error for EngineError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl Finalize for EngineError

fn finalize(&self)

Cleanup logic for a type.

impl From<EngineError> for JsError

fn from(value: EngineError) -> Self

Converts to this type from the input type.

impl From<PanicError> for EngineError

fn from(source: PanicError) -> Self

Converts to this type from the input type.

impl From<RuntimeLimitError> for EngineError

fn from(source: RuntimeLimitError) -> Self

Converts to this type from the input type.

impl PartialEq for EngineError

fn eq(&self, other: &EngineError) -> 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 Trace for EngineError

unsafe fn trace(&self, tracer: &mut Tracer)

Marks all contained Gcs.

unsafe fn trace_non_roots(&self)

Trace handles located in GC heap, and mark them as non root.

fn run_finalizer(&self)

Runs Finalize::finalize on this object and all contained subobjects.
