Types

type Fx

type Fx interface {
	// Initialize this feature extension to be running under this VM. Should
	// return an error if the VM is incompatible.
	Initialize(vm interface{}) error

	// Notify this Fx that the VM is in bootstrapping
	Bootstrapping() error

	// Notify this Fx that the VM is bootstrapped
	Bootstrapped() error

	// VerifyTransfer verifies that the specified transaction can spend the
	// provided utxo with no restrictions on the destination. If the transaction
	// can't spend the output based on the input and credential, a non-nil error
	// should be returned.
	VerifyTransfer(tx, in, cred, utxo interface{}) error

	// VerifyOperation verifies that the specified transaction can spend the
	// provided utxos conditioned on the result being restricted to the provided
	// outputs. If the transaction can't spend the output based on the input and
	// credential, a non-nil error should be returned.
	VerifyOperation(tx, op, cred interface{}, utxos []interface{}) error
}

Fx is the interface a feature extension must implement to support the AVM.
