}

func (*IMT) AddLeaf 

func (s *IMT) AddLeaf(deposit *ulxly.UlxlyBridgeEvent)

AddLeaf will take a given deposit and add it to the collection of leaves. It will also update the

func (*IMT) GetProof 

func (s *IMT) GetProof(depositNum uint32) Proof

GetProof will return an object containing the proof data necessary for verification

func (*IMT) GetRoot 

func (s *IMT) GetRoot(depositNum uint32) common.Hash

GetRoot will return the root for a particular deposit

func (*IMT) Init 

func (s *IMT) Init()

Init will allocate the objects in the IMT

func (*Proof) Check 

func (p *Proof) Check(roots []common.Hash) (common.Hash, error)

Check is a sanity check of a proof in order to make sure that the proof that was generated creates a root that we recognize. This was useful while testing in order to avoid verifying that the proof works or doesn't work onchain

func (*Proof) String 

func (p *Proof) String() string

String will create the json representation of the proof
