pub enum CaughtError<'js> {
    Error(Error),
    Exception(Exception<'js>),
    Value(Value<'js>),
}

An error type containing possible thrown exception values.

Value(Value<'js>)

Error was an exception but not an instance of Error.

Implementations

impl<'js> CaughtError<'js>

pub fn from_error(ctx: &Ctx<'js>, error: Error) -> Self

Create a CaughtError from an Error, retrieving the error value from Ctx if there was one.

pub fn catch<T>(ctx: &Ctx<'js>, error: Result<T>) -> CaughtResult<'js, T>

Turn a Result with Error into a result with CaughtError retrieving the error value from the context if there was one.

pub fn throw(self, ctx: &Ctx<'js>) -> Error

Put the possible caught value back as the current error and turn the CaughtError into Error

pub fn is_exception(&self) -> bool

Returns whether self is of variant CaughtError::Exception.

pub fn is_js_error(&self) -> bool

Returns whether self is of variant CaughtError::Exception or CaughtError::Value.

Trait Implementations

impl<'js> Debug for CaughtError<'js>

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

Formats the value using the given formatter.

impl<'js> Display for CaughtError<'js>

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

Formats the value using the given formatter.

impl<'js> Error for CaughtError<'js>

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

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.
