Functions

func SupportedTokenFormat 

func SupportedTokenFormat(precision uint64) (token2.Format, error)

Types

type AuditorService 

type AuditorService struct{}

func NewAuditorService 

func NewAuditorService() *AuditorService

func (*AuditorService) AuditorCheck 

func (s *AuditorService) AuditorCheck(ctx context.Context, request *driver.TokenRequest, metadata *driver.TokenRequestMetadata, anchor driver.TokenRequestAnchor) error

AuditorCheck verifies if the passed tokenRequest matches the tokenRequestMetadata fabtoken does not make use of AuditorCheck as the token request contains token information in the clear

type IssueService 

type IssueService struct {
	PublicParamsManager driver.PublicParamsManager
	WalletService       driver.WalletService
	Deserializer        driver.Deserializer
}

func NewIssueService 

func NewIssueService(publicParamsManager driver.PublicParamsManager, walletService driver.WalletService, deserializer driver.Deserializer) *IssueService

func (*IssueService) DeserializeIssueAction 

func (s *IssueService) DeserializeIssueAction(raw []byte) (driver.IssueAction, error)

DeserializeIssueAction un-marshals the passed bytes into an IssueAction If unmarshalling fails, then DeserializeIssueAction returns an error

func (*IssueService) Issue 

func (s *IssueService) Issue(ctx context.Context, issuerIdentity driver.Identity, tokenType token2.Type, values []uint64, owners [][]byte, opts *driver.IssueOptions) (driver.IssueAction, *driver.IssueMetadata, error)

Issue returns an IssueAction as a function of the passed arguments Issue also returns a serialization OutputMetadata associated with issued tokens and the identity of the issuer

func (*IssueService) VerifyIssue 

func (s *IssueService) VerifyIssue(tr driver.IssueAction, metadata []*driver.IssueOutputMetadata) error

VerifyIssue checks if the outputs of an IssueAction match the passed tokenInfos

	IdentityDeserializer driver.Deserializer
	OutputTokenFormat    token2.Format
}

func NewTokensService 

func NewTokensService(pp *setup.PublicParams, identityDeserializer driver.Deserializer) (*TokensService, error)

func (*TokensService) Deobfuscate 

func (s *TokensService) Deobfuscate(output driver.TokenOutput, outputMetadata driver.TokenOutputMetadata) (*token2.Token, driver.Identity, []driver.Identity, token2.Format, error)

Deobfuscate returns a deserialized token and the identity of its issuer

func (*TokensService) Recipients 

func (s *TokensService) Recipients(output driver.TokenOutput) ([]driver.Identity, error)

func (*TokensService) SupportedTokenFormats 

func (s *TokensService) SupportedTokenFormats() []token2.Format

type TokensUpgradeService 

type TokensUpgradeService struct{}

func (*TokensUpgradeService) CheckUpgradeProof 

func (s *TokensUpgradeService) CheckUpgradeProof(ch driver.TokensUpgradeChallenge, proof driver.TokensUpgradeProof, tokens []token2.LedgerToken) (bool, error)

func (*TokensUpgradeService) GenUpgradeProof 

func (s *TokensUpgradeService) GenUpgradeProof(ch driver.TokensUpgradeChallenge, tokens []token2.LedgerToken, witness driver.TokensUpgradeWitness) (driver.TokensUpgradeProof, error)

func (*TokensUpgradeService) NewUpgradeChallenge 

func (s *TokensUpgradeService) NewUpgradeChallenge() (driver.TokensUpgradeChallenge, error)

type TransferService 

type TransferService struct {
	Logger                  logging.Logger
	PublicParametersManager common.PublicParametersManager[*setup.PublicParams]
	WalletService           driver.WalletService
	TokenLoader             TokenLoader

) *TransferService

func (*TransferService) DeserializeTransferAction 

func (s *TransferService) DeserializeTransferAction(raw []byte) (driver.TransferAction, error)

DeserializeTransferAction un-marshals a TransferAction from the passed array of bytes. DeserializeTransferAction returns an error, if the un-marshalling fails.

func (*TransferService) Transfer 

func (s *TransferService) Transfer(ctx context.Context, anchor driver.TokenRequestAnchor, wallet driver.OwnerWallet, ids []*token.ID, outputs []*token.Token, opts *driver.TransferOptions) (driver.TransferAction, *driver.TransferMetadata, error)

Transfer returns a TransferAction as a function of the passed arguments It also returns the corresponding TransferMetadata

func (*TransferService) VerifyTransfer 

func (s *TransferService) VerifyTransfer(ctx context.Context, tr driver.TransferAction, outputMetadata []*driver.TransferOutputMetadata) error

VerifyTransfer checks the outputs in the TransferAction against the passed tokenInfos
