Types

type AccountedSeriesIter added in v0.7.1 

type AccountedSeriesIter struct {
	encoding.SeriesIterator
	// contains filtered or unexported fields
}

AccountedSeriesIter wraps a series iterator to track and enforce limits on datapoint usage. Datapoint usage is tracked on each call to Next().

func NewAccountedSeriesIter added in v0.7.1 

func NewAccountedSeriesIter(wrapped encoding.SeriesIterator, enforcer cost.ChainedEnforcer, scope tally.Scope) *AccountedSeriesIter

NewAccountedSeriesIter constructs an AccountedSeriesIter which uses wrapped as its source.

func (*AccountedSeriesIter) Close added in v0.7.1 

func (as *AccountedSeriesIter) Close()

Close closes the underlying iterator, and marks datapoints as released to our enforcer.

func (*AccountedSeriesIter) Err added in v0.7.1 

func (as *AccountedSeriesIter) Err() error

Err returns the underlying iterator's error if present, or any limit exceeded error.

func (*AccountedSeriesIter) Next added in v0.7.1
