func GetUsers

func GetUsers(ctx context.Context, userIDs []string) ([]*model.User, error)

GetUsers returns many users by ids efficiently

func Middleware

Types

type Loaders

type Loaders struct {
	UserLoader *dataloadgen.Loader[string, *model.User]
}

Loaders wrap your data loaders to inject via middleware
