Types

type ErrInvalidTransactionsInNewBlock 

type ErrInvalidTransactionsInNewBlock struct {
	InvalidTransactions []InvalidTransaction
}

ErrInvalidTransactionsInNewBlock indicates that some transactions in a new block are invalid

func (ErrInvalidTransactionsInNewBlock) Error 

func (e ErrInvalidTransactionsInNewBlock) Error() string

type ErrMissingParents 

type ErrMissingParents struct {
	MissingParentHashes []*externalapi.DomainHash
}

ErrMissingParents indicates a block points to unknown parent(s).

func (ErrMissingParents) Error 

func (e ErrMissingParents) Error() string

type ErrMissingTxOut 

type ErrMissingTxOut struct {
	MissingOutpoints []*externalapi.DomainOutpoint
}

ErrMissingTxOut indicates a transaction output referenced by an input either does not exist or has already been spent.

func (ErrMissingTxOut) Error 

func (e ErrMissingTxOut) Error() string

type InvalidTransaction 

type InvalidTransaction struct {
	Transaction *externalapi.DomainTransaction
	Error       error
}

InvalidTransaction is a struct containing an invalid transaction, and the error explaining why it's invalid.

func (InvalidTransaction) String 

func (invalid InvalidTransaction) String() string

type RuleError 

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

RuleError identifies a rule violation. It is used to indicate that processing of a block or transaction failed due to one of the many validation rules. The caller can use type assertions to determine if a failure was specifically due to a rule violation.

func (RuleError) Cause 

func (e RuleError) Cause() error

Cause satisfies the github.com/pkg/errors.Cause interface

func (RuleError) Error 

func (e RuleError) Error() string

Error satisfies the error interface and prints human-readable errors.

func (RuleError) Unwrap 

func (e RuleError) Unwrap() error

Unwrap satisfies the errors.Unwrap interface
