Trait naga::span::MapErrWithSpan

pub trait MapErrWithSpan<E, E2>: Sized {
    type Output: Sized;

    // Required method
    fn map_err_inner<F, E3>(self, func: F) -> Self::Output
       where F: FnOnce(E) -> WithSpan<E3>,
             E2: From<E3>;
}

Convenience trait for Result, adding a MapErrWithSpan::map_err_inner mapping to WithSpan::and_then.
