type TriePrefetcher 

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

TriePrefetcher is an active prefetcher, which receives accounts or storage items and does trie-loading of them. The goal is to get as much useful content into the caches as possible.

Note, the prefetcher's API is not thread safe.

func NewTriePrefetcher 

func NewTriePrefetcher(db ethstate.Database, root common.Hash, namespace string) *TriePrefetcher

NewTriePrefetcher

func (*TriePrefetcher) Close 

func (p *TriePrefetcher) Close()

Close iterates over all the subfetchers, aborts any that were left spinning and reports the stats to the metrics subsystem.

func (*TriePrefetcher) Copy 

func (p *TriePrefetcher) Copy() *TriePrefetcher

copy creates a deep-but-inactive copy of the trie prefetcher. Any trie data already loaded will be copied over, but no goroutines will be started. This is mostly used in the miner which creates a copy of it's actively mutated state to be sealed while it may further mutate the state.

func (*TriePrefetcher) Prefetch 

func (p *TriePrefetcher) Prefetch(root common.Hash, keys [][]byte)

prefetch schedules a batch of trie items to prefetch.

func (*TriePrefetcher) Trie 

func (p *TriePrefetcher) Trie(root common.Hash) ethstate.Trie

trie returns the trie matching the root hash, or nil if the prefetcher doesn't have it.

func (*TriePrefetcher) Used 

func (p *TriePrefetcher) Used(root common.Hash, used [][]byte)

used marks a batch of state items used to allow creating statistics as to how useful or wasteful the prefetcher is.
