Functions

func AuthComplexity

func AuthComplexity(authIntf verify.Verifiable) (gas.Dimensions, error)

AuthComplexity returns the complexity an authorization adds to a transaction. It does not include the typeID of the authorization. It does includes the complexity that the corresponding credential will add. It does not include the typeID of the credential.

func InputComplexity

func InputComplexity(ins ...*avax.TransferableInput) (gas.Dimensions, error)

InputComplexity returns the complexity inputs add to a transaction. It includes the complexity that the corresponding credentials will add.

func OutputComplexity

func OutputComplexity(outs ...*avax.TransferableOutput) (gas.Dimensions, error)

OutputComplexity returns the complexity outputs add to a transaction.

func OwnerComplexity

func OwnerComplexity(ownerIntf fx.Owner) (gas.Dimensions, error)

OwnerComplexity returns the complexity an owner adds to a transaction. It does not include the typeID of the owner.

func SignerComplexity

func SignerComplexity(s signer.Signer) (gas.Dimensions, error)

SignerComplexity returns the complexity a signer adds to a transaction. It does not include the typeID of the signer.

func TxComplexity

func TxComplexity(txs ...txs.UnsignedTx) (gas.Dimensions, error)
