Functions

func CreateParamsFromRequest

func CreateParamsFromRequest(req gen.CreateUserRequest) (username, password, role string)

CreateParamsFromRequest translates a generated CreateUserRequest into the primitive parameters Service.Create expects. This is not a pure 1:1 mapper — it also applies the API-level default role ("viewer") when the client omits it.

func ToResponse

func ToResponse(u *User) gen.User

ToResponse converts a domain User into the generated API model. Callers must guarantee u != nil — a nil User means "not found", which callers are expected to translate into 404 before calling ToResponse. This function panics on nil rather than silently returning an empty User, so a caller bug surfaces immediately instead of leaking as `{}` in a response.

PasswordHash is intentionally never mapped — gen.User has no such field.

func ToResponseList

func ToResponseList(users []*User) []gen.User

ToResponseList converts a slice of domain Users into generated API models.
