Types

type Chore added in v1.62.1

type Chore struct {
	TransactionCycle *sync2.Cycle
	// contains filtered or unexported fields
}

Chore periodically queries for new billing transactions from payment type.

architecture: Chore

func NewChore added in v1.62.1

func NewChore(log *zap.Logger, paymentTypes []PaymentType, transactionsDB TransactionsDB, interval time.Duration, disableLoop bool, bonusRate int64) *Chore

NewChore creates new chore.

func (*Chore) Close added in v1.62.1

func (chore *Chore) Close() (err error)

Close closes all underlying resources.

func (*Chore) Run added in v1.62.1

func (chore *Chore) Run(ctx context.Context) (err error)

Run runs billing transaction loop.

type Config added in v1.62.1

type Config struct {
	Interval    time.Duration `help:"billing chore interval to query for new transactions from all payment types" default:"15s"`
	DisableLoop bool          `help:"flag to disable querying for new billing transactions by billing chore" default:"true"`
}

Config stores needed information for billing service initialization.

type PaymentType added in v1.62.1

type PaymentType interface {
	// Source the source of the payment
	Source() string
	// Type the type of the payment
	Type() TransactionType
	// GetNewTransactions returns new transactions that occurred after the provided last transaction received.
	GetNewTransactions(ctx context.Context, lastTransactionTime time.Time, metadata []byte) ([]Transaction, error)
}

PaymentType is an interface which defines functionality required for all billing payment types. Payment types can include but are not limited to Bitcoin, Ether, credit or debit card, ACH transfer, or even physical transfer of live goats. In each case, a source, type, and method to get new transactions must be defined by the service, though metadata specific to each payment type is also supported (i.e. goat hair type).

type Transaction

type Transaction struct {
	ID          int64
	UserID      uuid.UUID
	Amount      currency.Amount
	Description string
	Source      string
	Status      TransactionStatus
	Type        TransactionType
	Metadata    []byte
	Timestamp   time.Time
	CreatedAt   time.Time
}

Transaction defines billing related transaction info that is stored in the DB.

type TransactionStatus added in v1.62.1

type TransactionStatus string

TransactionStatus indicates transaction status.

type TransactionType added in v1.62.1

type TransactionType string

TransactionType indicates transaction type.

type TransactionsDB

type TransactionsDB interface {
	// Insert inserts the provided primary transaction along with zero or more
	// supplemental transactions that. This is NOT intended for bulk insertion,
	// but rather to provide an atomic commit of one or more _related_
	// transactions.
	Insert(ctx context.Context, primaryTx Transaction, supplementalTx ...Transaction) (txIDs []int64, err error)
	// UpdateStatus updates the status of the transaction.
	UpdateStatus(ctx context.Context, txID int64, status TransactionStatus) error
	// UpdateMetadata updates the metadata of the transaction.
	UpdateMetadata(ctx context.Context, txID int64, metadata []byte) error
	// LastTransaction returns the timestamp and metadata of the last known transaction for given source and type.
	LastTransaction(ctx context.Context, txSource string, txType TransactionType) (time.Time, []byte, error)
	// List returns all transactions for the specified user.
	List(ctx context.Context, userID uuid.UUID) ([]Transaction, error)
	// GetBalance returns the current usable balance for the specified user.
	GetBalance(ctx context.Context, userID uuid.UUID) (currency.Amount, error)
}

TransactionsDB is an interface which defines functionality of DB which stores billing transactions.
