Common types

If more than one service requires the same data sctructure, it will be created as a common type.

Common types are imported from this repo.

This type stores artist info:

type Artist struct {
	Name    string
	URL     string
	ID      int
	Genre   string
	Country string
	Records []Record
}

When required services look for Artist info it will be stores in ArtistInfo type, because there can be more than one artist with the same name, ArtistInfo stores in Data first Artist found, the other artists will be stored in ExtraData.

type ArtistInfo struct {
	Data      Artist
	ExtraData []Artist
}

As many common types, this ArtistInfo type must be able to be encoded in order to be sent through queues.

This type stores Records info:

type RecordType int

const (
	FullLength RecordType = 1 << iota
	Demo
	EP
	Compilation
	Live
	BoxedSet
	Single
	Video
	Split
	Other
)

type Record struct {
	Name   string
	ID     int
	Year   int
	URL    string
	Type   RecordType
	Tracks []Track
}

This type store Tracks info:

type Track struct {
	Name    string
	Hours   int
	Minutes int
	Seconds int
}

Info retrieval jobs uses the same type:

const (
	ArtistName InfoRetrievalType = 1 << iota
	ArtistData
	AlbumName
	AlbumData
	AlbumWithArtistData
)

type InfoRetrieval struct {
	Type   InfoRetrievalType
	Data   []byte
	Artist string
	Album  string
}

All jobs, no matter its type, use this common type.

type JobType int

const (
	ArtistInfoRetrieval JobType = 1 << iota
	RecordInfoRetrieval
	JobInfoRetrieval
	Die
)

type Job struct {
	ID             int
	Finished       bool
	Status         bool
	Type           JobType
	LastOrigin     string
	RequiredOrigin string
	Data           []byte
	Result         []byte
	Error          string
}
