type DataSource

type DataSource struct {
	Users map[int64]Model
	// contains filtered or unexported fields
}

DataSource is our data store example.

func NewDataSource

func NewDataSource() *DataSource

NewDataSource returns a new user data source.

func (*DataSource) GetBy

func (d *DataSource) GetBy(query func(Model) bool) (user Model, found bool)

GetBy returns receives a query function which is fired for every single user model inside our imaginary database. When that function returns true then it stops the iteration.

It returns the query's return last known boolean value and the last known user model to help callers to reduce the loc.

But be carefully, the caller should always check for the "found" because it may be false but the user model has actually real data inside it.

It's actually a simple but very clever prototype function I'm think of and using everywhere since then, hope you find it very useful too.

func (*DataSource) GetByID

func (d *DataSource) GetByID(id int64) (Model, bool)

GetByID returns a user model based on its ID.

func (*DataSource) GetByUsername
