Types

type AllocBroadcaster added in v0.6.0 

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

AllocBroadcaster implements an allocation broadcast channel where each listener receives allocation updates. Pending updates are dropped and replaced by newer allocation updates, so listeners may not receive every allocation update. However this ensures Sends never block and listeners only receive the latest allocation update -- never a stale version.

func NewAllocBroadcaster added in v0.6.0 

func NewAllocBroadcaster(l hclog.Logger) *AllocBroadcaster

NewAllocBroadcaster returns a new AllocBroadcaster.

func (*AllocBroadcaster) Close added in v0.6.0 

func (b *AllocBroadcaster) Close()

Close closes the channel, disabling the sending of further allocation updates. Pending updates are still received by listeners. Safe to call concurrently and more than once.

func (*AllocBroadcaster) Listen added in v0.6.0 

func (b *AllocBroadcaster) Listen() *AllocListener

Listen returns a Listener for the broadcast channel. New listeners receive the last sent alloc update.

func (*AllocBroadcaster) Send added in v0.6.0 

func (b *AllocBroadcaster) Send(v *structs.Allocation) error

Send broadcasts an allocation update. Any pending updates are replaced with this version of the allocation to prevent blocking on slow receivers. Returns ErrAllocBroadcasterClosed if called after broadcaster is closed.

type AllocFileInfo added in v0.8.0

	Name     string

type AllocListener added in v0.6.0 

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

func (*AllocListener) Ch added in v0.6.0 

func (l *AllocListener) Ch() <-chan *structs.Allocation

func (*AllocListener) Close added in v0.6.0 

func (l *AllocListener) Close()

Close closes the Listener, disabling the receival of further messages. Safe to call more than once and concurrently with receiving on Ch.
