Not a rust aficionado: If you’re using error.As, wouldn’t you need essentially the same logic in Rust to match the error type and get access to the right fields

Not a rust aficionado: If you’re using error.As, wouldn’t you need essentially the same logic in Rust to match the error type and get access to the right fields? Seems like the big difference is the compiler knows the variants of the error. The trade off is that Rust modules are tightly coupled by the error type since you have wrap each one into the module’s own error type.
