Types

type EpochSpansCache

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

EpochSpansCache is used to store the spans needed on a per-epoch basis for slashing detection.

func NewEpochSpansCache

func NewEpochSpansCache(size int, onEvicted func(key interface{}, value interface{})) (*EpochSpansCache, error)

NewEpochSpansCache initializes the map and underlying cache.

func (*EpochSpansCache) Clear

func (c *EpochSpansCache) Clear()

Clear removes all keys from the SpanCache.

func (*EpochSpansCache) Delete

func (c *EpochSpansCache) Delete(epoch uint64) bool

Delete removes an epoch from the cache and returns if it existed or not. Performs the onEviction function before removal.

func (*EpochSpansCache) Get

func (c *EpochSpansCache) Get(epoch uint64) (map[uint64]types.Span, bool)

Get returns an ok bool and the cached value for the requested epoch key, if any.

func (*EpochSpansCache) Has

func (c *EpochSpansCache) Has(epoch uint64) bool

Has returns true if the key exists in the cache.

func (*EpochSpansCache) Set

func (c *EpochSpansCache) Set(epoch uint64, epochSpans map[uint64]types.Span)

Set the response in the cache.
