Functions

func MaxNetAddressPayload 

func MaxNetAddressPayload(pver uint32) uint32

MaxNetAddressPayload returns the max payload size for a bitcoin NetAddress based on the protocol version.

Types

type BloomUpdateType 

type BloomUpdateType uint8

BloomUpdateType specifies how the filter is updated when a match is found 

const (
	// BloomUpdateNone indicates the filter is not adjusted when a match is
	// found.
	BloomUpdateNone BloomUpdateType = 0

	// BloomUpdateAll indicates if the filter matches any data element in a
	// public key script, the outpoint is serialized and inserted into the
	// filter.
	BloomUpdateAll BloomUpdateType = 1

	// BloomUpdateP2PubkeyOnly indicates if the filter matches a data
	// element in a public key script and the script is of the standard
	// pay-to-pubkey or multisig, the outpoint is serialized and inserted
	// into the filter.
	BloomUpdateP2PubkeyOnly BloomUpdateType = 2
)

type InvType 

type InvType uint32

InvType represents the allowed types of inventory vectors. See InvVect. 

const (
	InvTypeError                InvType = 0
	InvTypeTx                   InvType = 1
	InvTypeBlock                InvType = 2
	InvTypeFilteredBlock        InvType = 3
	InvTypeWitnessBlock         InvType = InvTypeBlock | InvWitnessFlag
	InvTypeWitnessTx            InvType = InvTypeTx | InvWitnessFlag
	InvTypeFilteredWitnessBlock InvType = InvTypeFilteredBlock | InvWitnessFlag
)

These constants define the various supported inventory vector types.

func (InvType) String 

func (invtype InvType) String() string

String returns the InvType in human-readable form.

type InvVect 

type InvVect struct {
	Type InvType        // Type of data
	Hash chainhash.Hash // Hash of the data
}

InvVect defines a bitcoin inventory vector which is used to describe data, as specified by the Type field, that a server wants, has, or does not have to another server.

func NewInvVect 

func NewInvVect(typ InvType, hash *chainhash.Hash) *InvVect

NewInvVect returns a new InvVect using the provided type and hash.

type JaxNet 

type JaxNet uint32

JaxNet represents which bitcoin network a message belongs to. 

const (
	// MainNet represents the main jax network.
	MainNet JaxNet = 0xd9b4bef9

	// TestNet3 represents the test network (version 3).
	TestNet3 JaxNet = 0x0709110b

	// SimNet represents the simulation test network.
	SimNet JaxNet = 0x12141c16

	// FastTestNet represents the development jax network.
	FastTestNet JaxNet = 0x12121212
)

Constants used to indicate the message bitcoin network. They can also be used to seek to the next message when a stream's state is unknown, but this package does not provide that functionality since it's generally a better idea to simply disconnect clients that are misbehaving over TCP.

func (JaxNet) String 

func (n JaxNet) String() string

String returns the JaxNet in human-readable form.

type MessageError 

type MessageError struct {
	Func        string // Function name
	Description string // Human readable description of the issue
}

MessageError describes an issue with a message. An example of some potential issues are messages from the wrong bitcoin network, invalid commands, mismatched checksums, and exceeding max payloads.

This provides a mechanism for the caller to type assert the error to differentiate between general io errors such as io.EOF and issues that resulted from malformed messages.

func Error 

func Error(f string, desc string) *MessageError

messageError creates an error for the given function and description.

func (*MessageError) Error 

func (e *MessageError) Error() string

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

type NetAddress 

type NetAddress struct {
	// Last time the address was seen.  This is, unfortunately, encoded as a
	// uint32 on the wire and therefore is limited to 2106.  This field is
	// not present in the bitcoin version message (MsgVersion) nor was it
	// added until protocol version >= NetAddressTimeVersion.
	Timestamp time.Time

	// Bitfield which identifies the services supported by the address.
	Services ServiceFlag

	// IP address of the server.
	IP net.IP

	// Port the server is using.  This is encoded in big endian on the wire
	// which differs from most everything else.
	Port uint16
}

NetAddress defines information about a server on the network including the time it was last seen, the services it supports, its IP address, and port.

func NewNetAddress 

func NewNetAddress(addr *net.TCPAddr, services ServiceFlag) *NetAddress

NewNetAddress returns a new NetAddress using the provided TCP address and supported services with defaults for the remaining fields.

func NewNetAddressIPPort 

func NewNetAddressIPPort(ip net.IP, port uint16, services ServiceFlag) *NetAddress

NewNetAddressIPPort returns a new NetAddress using the provided IP, port, and supported services with defaults for the remaining fields.

func NewNetAddressTimestamp 

func NewNetAddressTimestamp(
	timestamp time.Time, services ServiceFlag, ip net.IP, port uint16) *NetAddress

NewNetAddressTimestamp returns a new NetAddress using the provided timestamp, IP, port, and supported services. The timestamp is rounded to single second precision.

func (*NetAddress) AddService 

func (na *NetAddress) AddService(service ServiceFlag)

AddService adds service as a supported service by the server generating the message.

func (*NetAddress) HasService 

func (na *NetAddress) HasService(service ServiceFlag) bool

HasService returns whether the specified service is supported by the address.

type RejectCode 

type RejectCode uint8

RejectCode represents a numeric value by which a remote server indicates why a message was rejected. 

const (
	RejectMalformed       RejectCode = 0x01
	RejectInvalid         RejectCode = 0x10
	RejectObsolete        RejectCode = 0x11
	RejectDuplicate       RejectCode = 0x12
	RejectNonstandard     RejectCode = 0x40
	RejectDust            RejectCode = 0x41
	RejectInsufficientFee RejectCode = 0x42
	RejectCheckpoint      RejectCode = 0x43
)

These constants define the various supported reject codes.

func (RejectCode) String 

func (code RejectCode) String() string

String returns the RejectCode in human-readable form.

type ServiceFlag 

type ServiceFlag uint64

ServiceFlag identifies services supported by a bitcoin server. 

const (
	// SFNodeNetwork is a flag used to indicate a server is a full node.
	SFNodeNetwork ServiceFlag = 1 << iota

	// SFNodeGetUTXO is a flag used to indicate a server supports the
	// getutxos and utxos commands (BIP0064).
	SFNodeGetUTXO

	// SFNodeBloom is a flag used to indicate a server supports bloom
	// filtering.
	SFNodeBloom

	// SFNodeWitness is a flag used to indicate a server supports blocks
	// and transactions including witness data (BIP0144).
	SFNodeWitness

	// SFNodeXthin is a flag used to indicate a server supports xthin blocks.
	SFNodeXthin

	// SFNodeBit5 is a flag used to indicate a server supports a service
	// defined by bit 5.
	SFNodeBit5

	// SFNodeCF is a flag used to indicate a server supports committed
	// filters (CFs).
	SFNodeCF

	// SFNode2X is a flag used to indicate a server is running the Segwit2X
	// software.
	SFNode2X
)

func (ServiceFlag) String 

func (f ServiceFlag) String() string

String returns the ServiceFlag in human-readable form.

type TimeSorter 

type TimeSorter []int64

TimeSorter implements sort.Interface to allow a slice of timestamps to be sorted.

func (TimeSorter) Len 

func (s TimeSorter) Len() int

Len returns the number of timestamps in the slice. It is part of the sort.Interface implementation.

func (TimeSorter) Less 

func (s TimeSorter) Less(i, j int) bool

Less returns whether the timstamp with index i should sort before the timestamp with index j. It is part of the sort.Interface implementation.

func (TimeSorter) Swap 

func (s TimeSorter) Swap(i, j int)

Swap swaps the timestamps at the passed indices. It is part of the sort.Interface implementation.
