Enum RuntimeError 

pub enum RuntimeError {
    Exception(Value),
    Reentered,
    Interrupted,
    Poisoned,
    Unsupported(&'static str),
    Compile(Error),
    OutOfMemory,
    Invariant(&'static str),
    Internal(String),
}

Why an API call failed.

Variants

Exception(Value)

JavaScript threw this value.

Reentered

An API call was made through a Context or Runtime from inside a host function or callback, which has its own scope.

Interrupted

The script was interrupted (InterruptHandle or Host::interrupt); no catch or finally of it ran.

Poisoned

A host function panicked while the runtime ran it; the runtime’s state is unknown and every later call fails.

Unsupported(&'static str)

The engine does not have this ("realms").

Compile(Error)

The front end rejected the source.

OutOfMemory

The heap cap was reached.

Invariant(&'static str)

The embedder broke one of the API’s preconditions.

Internal(String)

The engine failed internally.

Trait Implementations

impl Clone for RuntimeError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RuntimeError

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

Formats the value using the given formatter.

impl Display for RuntimeError

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

Formats the value using the given formatter.

impl Error for RuntimeError

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 From<Error> for RuntimeError

fn from(error: Error) -> Self

Converts to this type from the input type.

impl From<HeapError> for RuntimeError

fn from(error: HeapError) -> Self

Converts to this type from the input type.

impl From<JsStringError> for RuntimeError

fn from(error: JsStringError) -> Self

Converts to this type from the input type.

impl PartialEq for RuntimeError

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
