const BlockHeightUnknown = int32(-1)

BlockHeightUnknown is the value returned for a block height that is unknown. This is typically because the block has not been inserted into the main chain yet.

Functions

func AppDataDir

func AppDataDir(appName string, roaming bool) string

AppDataDir returns the path of appdata directory.

func NewTLSCertPair

func NewTLSCertPair(organization string, validUntil time.Time, extraHosts []string) (cert, key []byte, err error)

NewTLSCertPair returns a new PEM-encoded x.509 certificate pair based on a 521-bit ECDSA private key. The machine's local interface addresses and all variants of IPv4 and IPv6 localhost are included as valid IP addresses.

Types

type Amount

type Amount int64

Amount represents the base bitcoin monetary unit (colloquially referred to as a `Satoshi'). A single Amount is equal to 1e-8 of a bitcoin.

type Block

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

Block defines a bitcoin block that provides easier and more efficient manipulation of raw blocks. It also memoizes hashes for the block and its transactions on their first access so subsequent accesses don't have to repeat the relatively expensive hashing operations.

func NewBlock

func NewBlock(msgBlock *wire.MsgBlock) *Block

NewBlock returns a new instance of a bitcoin block given an underlying wire.MsgBlock. See Block.

func NewBlockFromBlockAndBytes

func NewBlockFromBlockAndBytes(msgBlock *wire.MsgBlock, serializedBlock []byte) *Block

NewBlockFromBlockAndBytes returns a new instance of a bitcoin block given an underlying wire.MsgBlock and the serialized bytes for it. See Block.

func NewBlockFromBytes

func NewBlockFromBytes(serializedBlock []byte) (*Block, error)

NewBlockFromBytes returns a new instance of a bitcoin block given the serialized bytes. See Block.

func NewBlockFromReader

func NewBlockFromReader(r io.Reader) (*Block, error)

NewBlockFromReader returns a new instance of a bitcoin block given a Reader to deserialize the block. See Block.

func (*Block) Bytes

func (b *Block) Bytes() ([]byte, error)

Bytes returns the serialized bytes for the Block. This is equivalent to calling Serialize on the underlying wire.MsgBlock, however it caches the result so subsequent calls are more efficient.

func (*Block) BytesNoWitness

func (b *Block) BytesNoWitness() ([]byte, error)

BytesNoWitness returns the serialized bytes for the block with transactions encoded without any witness data.

func (*Block) Hash

func (b *Block) Hash() *chainhash.Hash

Hash returns the block identifier hash for the Block. This is equivalent to calling blockHash on the underlying wire.MsgBlock, however it caches the result so subsequent calls are more efficient.

func (*Block) Height

func (b *Block) Height() int32

Height returns the saved height of the block in the block chain. This value will be BlockHeightUnknown if it hasn't already explicitly been set.

func (*Block) MsgBlock

func (b *Block) MsgBlock() *wire.MsgBlock

MsgBlock returns the underlying wire.MsgBlock for the Block.

func (*Block) SetHeight

func (b *Block) SetHeight(height int32)

SetHeight sets the height of the block in the block chain.

type OutOfRangeError

type OutOfRangeError string

OutOfRangeError describes an error due to accessing an element that is out of range.

func (OutOfRangeError) Error

func (e OutOfRangeError) Error() string

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