Functions ¶

func BigNumEqual ¶

func BigNumEqual(x, y *big.Int) bool

BigNumEqual returns true if x and y are equivalent ie. both nil or both contain the same value.

func IsForkTransition ¶

func IsForkTransition(fork *big.Int, parent *big.Int, current *big.Int) bool

IsForkTransition returns true if [fork] activates during the transition from [parent] to [current]. Note: this works for both block number and timestamp activated forks.

func IsForked ¶

func IsForked(s, head *big.Int) bool

IsForked returns whether a fork scheduled at block s is active at the given head block. Note: [s] and [head] can be either a block number or a block timestamp.

Types ¶

type MeteredCache ¶

type MeteredCache struct {
	*fastcache.Cache
	// contains filtered or unexported fields
}

MeteredCache wraps *fastcache.Cache and periodically pulls stats from it.

func NewMeteredCache ¶

func NewMeteredCache(size int, journal string, namespace string, updateFrequency uint64) *MeteredCache

NewMeteredCache returns a new MeteredCache that will update stats to the provided namespace once per each [updateFrequency] operations. Note: if [updateFrequency] is passed as 0, it will be treated as 1.

func (*MeteredCache) Del ¶

func (mc *MeteredCache) Del(k []byte)

func (*MeteredCache) Get ¶

func (mc *MeteredCache) Get(dst, k []byte) []byte

func (*MeteredCache) GetBig ¶

func (mc *MeteredCache) GetBig(dst, k []byte) []byte

func (*MeteredCache) Has ¶

func (mc *MeteredCache) Has(k []byte) bool

func (*MeteredCache) HasGet ¶

func (mc *MeteredCache) HasGet(dst, k []byte) ([]byte, bool)

func (*MeteredCache) Set ¶

func (mc *MeteredCache) Set(k, v []byte)

func (*MeteredCache) SetBig ¶

func (mc *MeteredCache) SetBig(k, v []byte)
