}

func (*SingleConsumerSession) CalculateExpectedLatency 

func (cs *SingleConsumerSession) CalculateExpectedLatency(timeoutGivenToRelay time.Duration) time.Duration

returns the expected latency to a threshold.

func (*SingleConsumerSession) CalculateQoS 

func (cs *SingleConsumerSession) CalculateQoS(latency, expectedLatency time.Duration, blockHeightDiff int64, numOfProviders int, servicersToCount int64)

func (*SingleConsumerSession) IsDataReliabilitySession added in v0.5.1 

func (scs *SingleConsumerSession) IsDataReliabilitySession() bool

validate if this is a data reliability session

type SingleProviderSession 

type SingleProviderSession struct {
	CuSum         uint64
	LatestRelayCu uint64
	SessionID     uint64

	RelayNum      uint64
	PairingEpoch  uint64
	BadgeUserData *ProviderSessionsEpochData
	// contains filtered or unexported fields
}

func (*SingleProviderSession) DisbandSession 

func (sps *SingleProviderSession) DisbandSession() error

func (*SingleProviderSession) GetOccupyingGuid 

func (sps *SingleProviderSession) GetOccupyingGuid() uint64

func (*SingleProviderSession) GetPairingEpoch 

func (sps *SingleProviderSession) GetPairingEpoch() uint64

func (*SingleProviderSession) IsBadgeSession 

func (sps *SingleProviderSession) IsBadgeSession() bool

func (*SingleProviderSession) IsPayingRelay 

func (sps *SingleProviderSession) IsPayingRelay() bool

to be used only when locked, otherwise can return wrong values is used to determine if the proof is beneficial and needs to be sent to rewardServer

func (*SingleProviderSession) PrepareDataReliabilitySessionForUsage 

func (sps *SingleProviderSession) PrepareDataReliabilitySessionForUsage(relayRequestTotalCU uint64) error

In case the user session is a data reliability we just need to verify that the cusum is the amount agreed between the consumer and the provider

func (*SingleProviderSession) PrepareSessionForUsage 

func (sps *SingleProviderSession) PrepareSessionForUsage(ctx context.Context, cuFromSpec, relayRequestTotalCU uint64, allowedThreshold float64) error

if this errors out the caller needs to unlock the session, this is not implemented inside because code between getting the session and this needs the same behavior

func (*SingleProviderSession) SetPairingEpoch 

func (sps *SingleProviderSession) SetPairingEpoch(epoch uint64)

func (*SingleProviderSession) VerifyLock 

func (sps *SingleProviderSession) VerifyLock() error

Verify the SingleProviderSession is locked when getting to this function, if its not locked throw an error
