Trait to implement how an error should be represented in JavaScript.

Note: it is not recommended to manually implement this type, but instead rather use the JsError macro.

Required Methods

fn get_class(&self) -> Cow<'static, str>

Represents the error class used in JavaScript side.

fn get_message(&self) -> Cow<'static, str>

Represents the error message used in JavaScript side.

fn get_additional_properties( &self, ) -> Vec<(Cow<'static, str>, Cow<'static, str>)>

Additional properties that should be defined on the error in JavaScript side.

fn as_any(&self) -> &dyn Any
