Generics can make your Go code slower

1. thiserror

   1 16 4,851 9.2 Rust

   derive(Error) for struct and enum error types

   

   > have you ever actually done that? I have, its not easy.

   Yes. I do it frequently. "#[derive(Error, Debug)]": https://github.com/dtolnay/thiserror#example

   Much easier than implementing the error interface in go.

   Rust is powerful enough to allow macros to remove annoying boiler-plate, and so most people using rust will grab one of the error-handling crates that are de-facto standard and remove the pain you're talking about.

   In go, it's not really possible to do this because the language doesn't provide such macros (i.e. the old third-party github.com/pkg/errors wanted you to implement 'Cause', but couldn't provide sugar like 'this-error' does for it because go is simply less powerful).

   Sweet! I've been using it for the same. Example game project (did it for a game jam): https://github.com/nikki93/raylib-5k -- in this case the Go gets transpiled to C++ and runs as WebAssembly too. Readme includes a link to play the game in the browser. game.gx.go and behaviors.gx.go kind of show the ECS style.

4. Gin

   Not to detract from your general point, but I believe that this specific situation was addresses in Go 1.18's GC pacer rework: https://github.com/golang/proposal/blob/master/design/44167-....
