Functions

func PayPerInterval 

func PayPerInterval(storeDriver store.BalanceStore, interval time.Duration, creditPerInterval *big.Int) *payPerInterval

PayPerInterval creates a balance Manager which implements a pay-per-interval scheme.

Types

type LowBalanceError added in v0.2.5 

type LowBalanceError struct {
	MinBalance     *big.Int
	CurrentBalance *big.Int
}

LowBalanceError is returned when the account's positive balance check fails.

func (LowBalanceError) Error added in v0.2.5 

func (err LowBalanceError) Error() string

type Manager 

type Manager interface {
	// OnClient is called when a client connects to the pool. If an error is
	// returned, the client is disconnected with the error.
	OnClient(node store.Node) error
	// OnUpdate is called every time the state of a node's peers is updated.
	OnUpdate(node store.Node, peers []store.Node) (store.Balance, error)
}

Manager is the minimal interface required to support a payment scheme. The payment implementation will receive handler calls. TODO: OnConnect, OnDisconnect, etc? OnConnect would be useful for time-based trials. TODO: Support error type that forces a disconnect (eg. trial expired?)

type NoBalance 

type NoBalance struct{}

NoBalance always returns an empty balance

func (NoBalance) OnClient added in v0.2.5 

func (b NoBalance) OnClient(node store.Node) error

func (NoBalance) OnUpdate 

func (b NoBalance) OnUpdate(node store.Node, peers []store.Node) (store.Balance, error)
