Justification for Rust not Supporting Function Overloading (directly)

[steveklabnik]

I think the framing is slightly off. I’m not aware of Rust ever having function overloading, so the question is not “why does Rust not support function overloading” but “what would allow Rust to support function overloading?” Features only get added if there’s a proposal, with justifications. I can’t remember, but I’m pretty sure there was never a proposal, and so therefore, no rejection of a proposal either.
