HOW

목표: Configure struct-level required validation in go-playground/validator using WithRequiredStructEnabled to prevent zero-value nested structs from silently passing
패키지: github.com/go-playground/validator/v10 10.30.3
심벌: validator.WithRequiredStructEnabled
validator.New
Validate.Struct
환경: go
생성일: 2026-08-17T12:35:13Z

validator.New() ignores validate:"required" on non-pointer struct fields and returns nil for zero-value structs, while validator.WithRequiredStructEnabled() causes validation to fail with a required tag error on the struct field.
Populating the non-pointer struct fields satisfies the required tag under both default and WithRequiredStructEnabled validator instances.
Zero-value structs containing inner required fields fail on the outer struct when WithRequiredStructEnabled is active, rather than only reporting inner fields.
