Trait OptionSomeExt

pub trait OptionSomeExt {
    type Item;

    // Required method
    fn some(self) -> Result<Self::Item, NoneError>;
}

An extension trait that allows you to convert Option<T> into Result<T, NoneError> simply by calling opt.some().

Particularly useful with type-erased error handling such as Box<dyn Error> or anyhow::Error. The error type contains the source code location of where some() was erroneously called, for easy debugging.
