}Expand description
Polymorphic exception type that corresponds to Ruby’s Exception.
All types that implement RubyException can be raised with
error::raise. Rust code can re-raise a trait object to
propagate exceptions from native code back into the interpreter.
Required Methods§
sourcefn message(&self) -> Cow<'_, [u8]>
fn message(&self) -> Cow<'_, [u8]>
Message of the Exception.
This value is a byte slice since Ruby Strings are equivalent to
Vec<u8>.
sourcefn vm_backtrace(
&self,
interp: &mut Artichoke
) -> Option<Vec<Vec<u8, Global>, Global>>
fn vm_backtrace( &self, interp: &mut Artichoke ) -> Option<Vec<Vec<u8, Global>, Global>>
Optional backtrace specified by a Vec of frames.
sourcefn as_mrb_value(&self, interp: &mut Artichoke) -> Option<mrb_value>
fn as_mrb_value(&self, interp: &mut Artichoke) -> Option<mrb_value>
Return a raise-able sys::mrb_value.
