Functions

func Couple

func Couple(in types.Producer, out types.Consumer) error

Couple - Connect a producer to a consumer.

Types

type ClosablePool

type ClosablePool struct {
	// contains filtered or unexported fields
}

ClosablePool - Keeps a reference to a pool of closable types and closes them in tiers.

func NewClosablePool

func NewClosablePool() *ClosablePool

NewClosablePool - Create a fresh pool of closable types.

func (*ClosablePool) Add

func (c *ClosablePool) Add(tier int, closable types.Closable)

Add - Adds a closable type to the pool, tiers are used to partition and order the closing of types (starting at the lowest tier and working upwards). Closable types in a single tier are closed in the order that they are added.

func (*ClosablePool) Close

func (c *ClosablePool) Close(timeout time.Duration) error

Close - Attempt to close and clean up all stored closables in the determined order. If the timeout is met whilst working through the pool there is no indication of how far the pool has been progressed, thus this timeout should only be used for preventing severe blocking of a service.
