Types

type EpochQuery

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

EpochQuery represents the epoch information for an invalid state snapshot query.

func (EpochQuery) Current

func (e EpochQuery) Current() (protocol.CommittedEpoch, error)

func (EpochQuery) NextCommitted

func (e EpochQuery) NextCommitted() (protocol.CommittedEpoch, error)

func (EpochQuery) NextUnsafe

func (e EpochQuery) NextUnsafe() (protocol.TentativeEpoch, error)

func (EpochQuery) Previous

func (e EpochQuery) Previous() (protocol.CommittedEpoch, error)

type Params

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

Params represents parameters for an invalid state snapshot query.

func (Params) ChainID

func (p Params) ChainID() flow.ChainID

func (Params) SporkID

func (p Params) SporkID() flow.Identifier

func (Params) SporkRootBlockHeight

func (p Params) SporkRootBlockHeight() uint64

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

func NewSnapshot(err error) *Snapshot

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

func NewSnapshotf

func NewSnapshotf(msg string, args ...interface{}) *Snapshot

NewSnapshotf is NewSnapshot with ergonomic error formatting.

func (*Snapshot) Descendants

func (u *Snapshot) Descendants() ([]flow.Identifier, error)

func (*Snapshot) EpochPhase
