Functions

func AddNATSMessageHandler

func AddNATSMessageHandler(
	service *res.Service,
	subject string,
	handler func(message *nats.Msg) error,
) error

AddNATSMessageHandler to a RES service. The handler will be called for each message received on the given subject.

func CompareModels

func CompareModels[T any](previous, current T) map[string]any

CompareModels and returns a map of the differences between them. The result can be used with the https://pkg.go.dev/github.com/jirenius/go-res#Request.ChangeEvent method.

func HandleCollectionQueryRequest

func HandleCollectionQueryRequest[T any](
	service *res.Service,
	rid string,
	handler func(request res.QueryRequest) ([]T, error),
) error

func HandleModelQueryRequest

func HandleModelQueryRequest[T any](
	service *res.Service,
	rid string,
	handler func(request res.QueryRequest) (T, error),
) error

func MapRefs

func MapRefs[E any, S []E](s S, f func(e E) res.Ref) []res.Ref

MapRefs from a slice of elements. The function f is called for each element in the slice, and the resulting reference is added to the result.
