Types ¶
type Epoch ¶
type Epoch struct {
// contains filtered or unexported fields
}
Epoch represents an epoch that does not exist or could not be retrieved.
func NewEpoch ¶
NewEpoch returns a new invalid epoch, containing an error describing why the epoch could not be retrieved. The following are expected errors when constructing an invalid Epoch:
- protocol.ErrNoPreviousEpoch - if the epoch represents a previous epoch which does not exist. This happens when the previous epoch is queried within the first epoch of a spork.
- protocol.ErrNextEpochNotSetup - if the epoch represents a next epoch which has not been set up. This happens when the next epoch is queried within the EpochStaking phase of any epoch.
- state.ErrUnknownSnapshotReference - if the epoch is queried from an unresolvable snapshot.
- generic error in case of unexpected critical internal corruption or bugs
func (*Epoch) ClusterByChainID ¶ added in v0.26.1
func (*Epoch) Clustering ¶

func (*Epoch) FinalHeight ¶ added in v0.30.0
func (*Epoch) FirstHeight ¶ added in v0.30.0
func (*Epoch) InitialIdentities ¶
func (u *Epoch) InitialIdentities() (flow.IdentityList, error)
func (*Epoch) RandomSource ¶
type Epochs ¶
type Epochs struct {
// contains filtered or unexported fields
}
Epochs is an epoch query for an invalid snapshot.
type Params ¶ added in v0.23.2
type Params struct {
// contains filtered or unexported fields
}
Params represents parameters for an invalid state snapshot query.
func (Params) EpochCommitSafetyThreshold ¶ added in v0.29.0
func (Params) ProtocolVersion ¶ added in v0.23.2
func (Params) SporkRootBlockHeight ¶ added in v0.29.6
type Snapshot ¶
type Snapshot struct {
// contains filtered or unexported fields
}
Snapshot represents a snapshot that does not exist or could not be queried.
func NewSnapshot ¶
NewSnapshot returns a new invalid snapshot, containing an error describing why the snapshot could not be retrieved. The following are expected errors when constructing an invalid Snapshot:
- state.ErrUnknownSnapshotReference if the reference point for the snapshot (height or block ID) does not resolve to a queriable block in the state.
- generic error in case of unexpected critical internal corruption or bugs
