Fair point re: Zig vs Rust, but my larger point was about exceptions by any other name, in the linked article:
"Instead, when returning an error, rather than jumping to the return address, we look it up in the side table to find a corresponding error recovery address, and jump to that. Stack unwinding!
The bold claim is that unwinding is the optimal thing to do! .."
- necubi 11mo agoIf by "exceptions" you're talking about stack unwinding (as opposed to the language-level control flow constructs like throw/catch) then Rust has always had that with panics and panic=unwind.
- stmw 11mo agoI am talking about the wider category that includes stack unwinding as an error handling pattern for errors outside of catastrophic. T My opinion (which one need not approve of) is that it asymptotically approaches the language-level control flow constructs.
