How to ensure required fields in struct consistently?

1. validator

   1 76 20,058 8.5 Go

   :100:Go Struct and Field validation, including Cross Field, Cross Struct, Map, Slice and Array diving

   

   Use https://github.com/go-playground/validator, which would just simply require you to add a tag to your struct for those fields.

3. semgrep

   2 106 15,844 9.8 OCaml

   Lightweight static analysis for many languages. Find bug variants with patterns that look like source code.

   

   FWIW you can probably write a semgrep rule or something, to find all struct literals which don't mention a specific field.

4. mapstructure

   3 18 7,867 0.0 Go

   Discontinued Go library for decoding generic map values into native Go structures and vice versa.

   I'm doing it by validating a map[string]any first then putting it into a structure using mapstructure. It covers most use-cases and offers the most flexibility, at the expense of a bit of performance.

5. go-exhaustruct

   4 7 201 8.2 Go

   golang analyzer that finds structures with uninitialized fields

   

   Have you consider adding a linter as part of you build process to detect those un-initialized fields? Like go-exhaustruct, (it's already included in golangci-lint if you use that already)
