pub enum InvokeError<E: SelfError> {
    SelfError(E),
    Downstream(RuntimeError),
}
Expand description

This enum is to help with designing intuitive error abstractions. Each engine module can have its own SelfError, but can also wrap arbitrary downstream errors. Ultimately these errors get flattened out to a RuntimeError anyway.
