Trait artichoke_backend::error::RubyException

pub trait RubyException: Error + 'static {
    fn message(&self) -> Cow<'_, [u8]>;
    fn name(&self) -> Cow<'_, str>;
    fn vm_backtrace(&self, interp: &mut Artichoke) -> Option<Vec<Vec<u8>>>;
    fn as_mrb_value(&self, interp: &mut Artichoke) -> Option<mrb_value>;
}

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

fn message(&self) -> Cow<'_, [u8]>

Message of the Exception.

This value is a byte slice since Ruby Strings are equivalent to Vec<u8>.

fn name(&self) -> Cow<'_, str>

Class name of the Exception.

fn vm_backtrace(&self, interp: &mut Artichoke) -> Option<Vec<Vec<u8>>>

Optional backtrace specified by a Vec of frames.

fn as_mrb_value(&self, interp: &mut Artichoke) -> Option<mrb_value>

Return a raiseable sys::mrb_value.

Trait Implementations

impl<'_> Error for &'_ dyn RubyException

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

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

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
