So very concise. And this is not even including the error wrapping that is recommended.
- torginus 3mo agoFirst, this is legal: if err := do_something() ;err != nil { return nil, err } Not horrible imo. But I've found that verbose error handling and explicit errors made me consider which parts of the code can return err, and reorganize code around that - with that I've been able to eliminate most 'err' from my codebase. Like, if you go by function: ReadData(has err)-> ParseData(has err) -> ProcessData(no err) Instead of having functions that can fail dynamically all over your codebase.
