Struct Error 

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

An engine error. JavaScript exceptions will eventually carry a heap value; this type is also usable before a context exists (lexer and decoder errors).

Implementations

impl Error

pub fn new(kind: ErrorKind, message: impl Into<String>) -> Self

pub fn from_native_message( kind: ErrorKind, native_message: NativeErrorMessage, ) -> Self

pub fn syntax(message: impl Into<String>, span: SourceSpan) -> Self

pub fn unsupported(message: impl Into<String>, span: SourceSpan) -> Self

pub fn internal(message: impl Into<String>) -> Self

pub const fn kind(&self) -> ErrorKind

pub fn message(&self) -> &str

pub fn native_message(&self) -> Option<&NativeErrorMessage>

pub const fn span(&self) -> Option<SourceSpan>

pub const fn with_span(self, span: SourceSpan) -> Self

Trait Implementations

impl Clone for Error

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 Error

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

Formats the value using the given formatter.

impl Display for Error

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

impl Eq for Error

impl Error for Error

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<JsStringError> for Error

fn from(error: JsStringError) -> Self

Converts to this type from the input type.

impl PartialEq for Error

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

Equality operator ==.

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

Inequality operator !=.
