Types

type AttCaches

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

AttCaches defines the caches used to satisfy attestation pool interface. These caches are KV store for various attestations such are unaggregated, aggregated or attestations within a block.

func NewAttCaches

func NewAttCaches() *AttCaches

NewAttCaches initializes a new attestation pool consists of multiple KV store in cache for various kind of attestations.

func (*AttCaches) AggregateUnaggregatedAttestations

func (p *AttCaches) AggregateUnaggregatedAttestations() error

AggregateUnaggregatedAttestations aggregates the unaggregated attestations and saves the newly aggregated attestations in the pool. It tracks the unaggregated attestations that weren't able to aggregate to prevent the deletion of unaggregated attestations in the pool.

func (*AttCaches) AggregatedAttestationCount

func (p *AttCaches) AggregatedAttestationCount() int

AggregatedAttestationCount returns the number of aggregated attestations key in the pool.

func (*AttCaches) AggregatedAttestations

func (p *AttCaches) AggregatedAttestations() []*ethpb.Attestation

AggregatedAttestations returns the aggregated attestations in cache.

func (*AttCaches) AggregatedAttestationsBySlotIndex

func (p *AttCaches) AggregatedAttestationsBySlotIndex(slot uint64, committeeIndex uint64) []*ethpb.Attestation

AggregatedAttestationsBySlotIndex returns the aggregated attestations in cache, filtered by committee index and slot.

func (*AttCaches) BlockAttestations

func (p *AttCaches) BlockAttestations() []*ethpb.Attestation

BlockAttestations returns the block attestations in cache.

func (*AttCaches) DeleteAggregatedAttestation

func (p *AttCaches) DeleteAggregatedAttestation(att *ethpb.Attestation) error

DeleteAggregatedAttestation deletes the aggregated attestations in cache.

func (*AttCaches) DeleteBlockAttestation

func (p *AttCaches) DeleteBlockAttestation(att *ethpb.Attestation) error

DeleteBlockAttestation deletes a block attestation in cache.

func (*AttCaches) DeleteForkchoiceAttestation

func (p *AttCaches) DeleteForkchoiceAttestation(att *ethpb.Attestation) error

DeleteForkchoiceAttestation deletes a forkchoice attestation in cache.

func (*AttCaches) DeleteUnaggregatedAttestation

func (p *AttCaches) DeleteUnaggregatedAttestation(att *ethpb.Attestation) error

DeleteUnaggregatedAttestation deletes the unaggregated attestations in cache.

func (*AttCaches) ForkchoiceAttestations

func (p *AttCaches) ForkchoiceAttestations() []*ethpb.Attestation

ForkchoiceAttestations returns the forkchoice attestations in cache.

func (*AttCaches) HasAggregatedAttestation

func (p *AttCaches) HasAggregatedAttestation(att *ethpb.Attestation) (bool, error)

HasAggregatedAttestation checks if the input attestations has already existed in cache.

func (*AttCaches) SaveAggregatedAttestation

func (p *AttCaches) SaveAggregatedAttestation(att *ethpb.Attestation) error

SaveAggregatedAttestation saves an aggregated attestation in cache.

func (*AttCaches) SaveAggregatedAttestations

func (p *AttCaches) SaveAggregatedAttestations(atts []*ethpb.Attestation) error

SaveAggregatedAttestations saves a list of aggregated attestations in cache.

func (*AttCaches) SaveBlockAttestation

func (p *AttCaches) SaveBlockAttestation(att *ethpb.Attestation) error

SaveForkchoiceAttestations saves a list of forkchoice attestations in cache.

func (*AttCaches) SaveUnaggregatedAttestation

func (p *AttCaches) SaveUnaggregatedAttestation(att *ethpb.Attestation) error

SaveUnaggregatedAttestation saves an unaggregated attestation in cache.

func (*AttCaches) SaveUnaggregatedAttestations

func (p *AttCaches) SaveUnaggregatedAttestations(atts []*ethpb.Attestation) error
