Types

type Encoder 

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

func NewEncoder 

func NewEncoder(c context.T, sizeLimit int, gcTimer time.Duration) *Encoder

NewEncoder creates a cache.Encoder that maintains a cache of already decoded JSON bytes of events to prevent doubling up of both decoding work and JSON bytes usage for multiple concurrent requests of overlapping events by clients.

func (*Encoder) Get 

func (d *Encoder) Get(evId eventid.T) (b []byte)

Get retrieves the encoded JSON for a given event if it is cached. If it returns a nil slice, the caller should fetch the event binary from the database and use Put to store it for the next call.

func (*Encoder) Put 

func (d *Encoder) Put(ev *event.T) (j []byte, err error)

Put stores an event's encoded JSON form for access by concurrent client requests. Call this with an event decoded from the database so that concurrent queries that match it can avoid repeated decode/allocate steps.

type Event 

type Event struct {
	JSON []byte
	// contains filtered or unexported fields
}
