Implementations

impl Error

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

Create a new RuntimeError with msg.

pub fn iter_break<T>(val: Option<T>) -> Selfwhere
    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) -> boolwhere
    T: Deref<Target = Value> + Module,
