Types ¶
type UserService ¶
type UserService struct {
// contains filtered or unexported fields
}
UserService represent the service that manage user without implementation detail, this aim to provide API that will be exposed to the handler (HTTP, GRPC)
This part is really up to the implementation detail and expectation. For instance, we could have this service at the handler level if we plan to only use one api exposure.
func (*UserService) Create ¶
func (u *UserService) Create(ctx context.Context, usr *User) error
Create creates a new user. If the user already exist in the storage, ErrUserAlreadyExist will be returned.
type UserStorage ¶
type UserStorage interface {
Fetch(ctx context.Context, id string) (*User, error)
Create(ctx context.Context, u *User) error
Delete(ctx context.Context, id string) error
}
UserStorage defines how we store a user. By definition, it is decouple from any backend implementation and its design to be an abstraction of an actual storage.
