Types

type BasicMerkletree

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

func New

func New(vals []Value, h hasher.Hasher) (*BasicMerkletree, error)

func (*BasicMerkletree) Reconstruct

func (t *BasicMerkletree) Reconstruct(valsInterface ...interface{}) error

Reconstruct construct merkletree again

func (*BasicMerkletree) Root

func (t *BasicMerkletree) Root() []byte

Root return merkletree's root hash

func (*BasicMerkletree) VerifyRoot

func (t *BasicMerkletree) VerifyRoot() bool

func (*BasicMerkletree) VerifyValue

func (t *BasicMerkletree) VerifyValue(exceptedRoot []byte, valInterface interface{}) bool

type ErrEmptyValues

type ErrEmptyValues struct{}

ErrEmptyValues indicated that merkletree init with empty values

func (*ErrEmptyValues) Error

func (err *ErrEmptyValues) Error() string

type ErrInvalidValueType

type ErrInvalidValueType struct{}

ErrInvalidValueType indicated the received value isn't Value interface

func (*ErrInvalidValueType) Error

func (err *ErrInvalidValueType) Error() string

type Value

type Value interface {
	Hash() ([]byte, error)
	Equals(other interface{}) bool
}

Value represents the data that is stored in the tree. Any type which implements the interface can stored in the MerkleTree
