Struct JsFault 

pub struct JsFault { /* private fields */ }

A failure on the JavaScript side of a walk or a build: a getter threw, a string had an unpaired surrogate, a value was of a type that cannot be encrypted, a tree was too deep.

A napi Error is not Send, so it cannot travel inside a SourceError; this carries its status and reason, which is all a caller needs to hand it back to JavaScript. A Status::PendingException means the original JavaScript exception is still pending in the engine, and returning this error lets it surface unchanged.

Implementations

impl JsFault

pub fn status(&self) -> Status

The napi status of the failure. Status::PendingException means a JavaScript exception is still pending: return this error to JavaScript before running any more JavaScript, so the exception surfaces as it was thrown.

pub fn reason(&self) -> &str

The failure’s message.

pub fn from_source(error: &SourceError) -> Error

The napi error for a source error, which is a JsFault when the source was a JavaScript value and some other error otherwise.

Trait Implementations

impl Clone for JsFault

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 JsFault

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

Formats the value using the given formatter.

impl Display for JsFault

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

impl Eq for JsFault

impl Error for JsFault

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 Error for JsFault

fn source(error: SourceError) -> Self

Wrap a failure that came from the source, not the sink.

impl From<Error> for JsFault

fn from(error: Error) -> Self

Converts to this type from the input type.

impl From<JsFault> for Error

fn from(fault: JsFault) -> Self

Converts to this type from the input type.

impl PartialEq for JsFault

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

Equality operator ==.

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

Inequality operator !=.
