Struct UIError

pub struct UIError {
    pub inner: Rc<dyn UIErrorTrait>,
}

A wrapping struct for any UI’s error type

To use the wrapper implement UIErrorTrait on the error type to wrap and use .into() to convert it into this UIError wrapper.

Fields

inner: Rc<dyn UIErrorTrait>

Implementations

impl UIError

pub fn downcast_ref<T: UIErrorTrait>(&self) -> Option<&T>

Helper for downcasting into the internal error type

Due to how finnicky this is to get right, with coercing the Rc into &T before downcasting, I very much recommend using this helper.
