Implementations

impl Error

pub fn new<T>(class: ExceptionClass, msg: T) -> Self where
    T: Into<Cow<'static, str>>, 

Create a new Error that can be raised as a Ruby Exception with msg.

pub fn runtime_error<T>(msg: T) -> Self where
    T: Into<Cow<'static, str>>, 

Create a new RuntimeError with msg.

pub fn iter_break<T>(val: Option<T>) -> Self where
    T: Into<Value>, 

Create a new error that will break from a loop when returned to Ruby.

pub fn is_kind_of<T>(&self, class: T) -> bool where
    T: Deref<Target = Value> + Module, 

Matches the internal Exception against class with same semantics as Ruby’s rescue.
