func (*Branches) BranchKnowsTransaction ¶

func (b *Branches) BranchKnowsTransaction(branchID, txid base.TransactionID) bool

func (*Branches) ChainLines ¶

func (b *Branches) ChainLines(tipOrig base.TransactionID, prefix ...string) *lines.Lines

ChainLines for debugging

func (*Branches) Get ¶

func (b *Branches) Get(branchTxID base.TransactionID) *multistate.BranchData

func (*Branches) GetStateReaderForTheBranch ¶

func (b *Branches) GetStateReaderForTheBranch(branchID base.TransactionID) multistate.IndexedStateReader

GetStateReaderForTheBranch returns a state reader for the branch or nil if the state does not exist. If the branch is before the snapshot and branch ChainID is known in the snapshot state, it returns the snapshot state (which always exists)

func (*Branches) IsDescendantBranch ¶

func (b *Branches) IsDescendantBranch(descendant, ancestor base.TransactionID) (sameLineage bool, isDescendant bool)

IsDescendantBranch returns:

compatible = true -> then isDescendentOf=true if branch1 known branch2 and false otherwise
compatible = false -> branches not in the same chain and isDescendentOf is undefined

func (*Branches) LedgerCoverage ¶

func (b *Branches) LedgerCoverage(branchID base.TransactionID) uint64

LedgerCoverage strictly speaking, is non-deterministic if the snapshot is after the genesis However:

• if branchID is far enough (63 slots), it is guaranteed to be the real value and therefore deterministic
• if the snapshot is N slots behind the branchID, it is guaranteed that the returned value differs from the real value no more than by 1/2^N

func (*Branches) SequencerOutputID ¶

func (b *Branches) SequencerOutputID(branchID base.TransactionID) (base.OutputID, bool)

func (*Branches) SnapshotBranchID ¶

func (b *Branches) SnapshotBranchID() base.TransactionID

func (*Branches) SnapshotKnowsTransaction ¶

func (b *Branches) SnapshotKnowsTransaction(txid base.TransactionID) bool

func (*Branches) SnapshotSlot ¶

func (b *Branches) SnapshotSlot() uint32

func (*Branches) Supply ¶

func (b *Branches) Supply(branchID base.TransactionID) uint64

func (*Branches) TransactionIsInSnapshotState ¶

func (b *Branches) TransactionIsInSnapshotState(txid base.TransactionID) bool
