  • derive_more: can it be used to handle operator overloads for borrowed references?
    1 project | /r/rust | 11 Apr 2023
    Is there a way to use derive_more to handle the generation of binary operators with one or both referenced operands? For example, avoiding having to do this macro dance for every combination of MyVal and &MyVal, for every operator needed:
  • Is there a convenient way to convert a struct<T> (where all fields are of type T) into struct<U> where U: From<T>?

    This fails to compile. Looking at the implementation for that macro I don't see a way to use it that would work: https://github.com/JelteF/derive_more/blob/master/impl/src/from.rs

    tl;dr you can put commit hashes in the place where the parent comment put tags.

    The PR interface actually exposes this for force-pushes, but the UI discovery for this is horrible. It turns out that the "force-pushed" part in the little message in the github UI is actually a link. This link points to the diff between the old and the new HEAD of the branch.

    As an example you can look at this PR:

    It has this little message somewhere down the page:

    Monadic-Cat force-pushed the add-unwrap branch from e130dbe to 25235aa 4 months ago

    If you then click that link you go to the "compare" page, which shows the diff between the two commits:

    https://github.com/JelteF/derive_more/compare/e130dbe6b2a429...

    Disclaimer: I'm a Micrsoft employe, but don't work on Github. I'm a daily user of Github though.
