After reading this thread and the other recent thread(s) about panics I re-re-read the panic macro docs and see this
This macro should be used to avoid proceeding using incorrect values, such as from external sources.
and I think that could be understood as saying use a panic for an invalid server request.
That same doc panic in std - Rust also says, immediately before that statement:
Result
enum is often a better solution for recovering from errors than using thepanic!
macro.
I think that could be understood as saying Result
is a better way to handle invalid server requests.
I would interpret "external sources" as something far more serious, like a hardware register that is not in the correct state. Or some nonsense returned from calling a C function.
Clearly statement is just a heads up that there is a thing called Result
rather than any suggested rule about when to use either.
