Trait error_annotation::Annotatable

pub trait Annotatable: Sized {
    fn merge_annotation<I>(ea: ErrorAnnotation<Self, I>) -> Self
    where
        I: Display;
}

An Annotatable error type is can convert an ErrorAnnotation with Self as the source type back into Self, provided the annotated info implements std::fmt::Display.

A prime example is the std::io::Error impl, which can be used to convert any annotation on a std::io::Error back into a std::io::Error, as the crate-level example demonstrates.

The conversion provided by implementations of Annotatable is typically conveniently accomplished via AnnotateResult::annotate_err_into.
