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

Message of the Exception.

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

Class name of the Exception.

Optional backtrace specified by a Vec of frames.

Return a raise-able sys::mrb_value.
