func ExtractFields ¶

func ExtractFields(input any, targetTags []string) map[string]any

ExtractFields extracts the values of struct fields that have a "json" tag matching any of the targetTags. It accepts a struct or a pointer to a struct. Unexported fields, fields without a "json" tag, and fields with a json tag of "-" are ignored. It correctly handles json tag options like "omitempty" by only considering the name part of the tag.
