Overview

Package data aims to provides all the data types that are needed to build tools, clients and servers for use on the Ripple network.

Ledger

The ledger is a mixture of various data types, all persisted in the form of a key and value. The value contains a node, and some nodes refer to other nodes by their index. An index may or may not be equivalent to a node's key. A ledger consists of a LedgerHeader as the root of two trees, one for the transactions in that ledger and one for the state of all accounts at that point in time.

A ledger refers to its predecessor, which has a completely different tree for its transactions, but the account state tree will share most of its nodes with its successors and predecessors.

The full ledger consists of a sequence of such ledgers, each referring to, and dependent on its predecessor.

Important terms are key, value, index, hash and node. Keys, indexes and hashes are always 32 bytes in length and involve the use of the SHA512 cryptographic hash algorithm, discarding the last 32 bytes of the resulting hash. Sometimes they are the same thing, sometimes not.

LedgerHeader

This is the root of the two trees for a single ledger. It contains information about the ledger and its predecessor. A ledger header node is never reused between ledgers. 

Node:	Simple big-endian binary encoding of LedgerHeader
Index:  SHA512Half of HP_LEDGER_MASTER:Node
Hash:	Same as Index

Key:	Index
Value:	LedgerSequence:LedgerSequence:NT_LEDGER:HP_LEDGER_MASTER:Node

Inner Node

This is a node in either the transaction or account state tree which contains up to 16 hashes of other nodes. The position of the hash represents a 4 bit nibble of the index that is being searched for in the tree. An account state inner node may be reused between ledgers, a transaction inner node will never be reused. 

Node:	Simple big-endian binary encoding of 16 x 32 byte hashes
Index:	SHA512Half of HP_INNER_NODE:Node
Hash:	Same as Index

Key: 	Index
Value:	LedgerSequence:LedgerSequence:NT_ACCOUNT_NODE or NT_TRANSACTION_NODE:HP_INNER_NODE:Node

TransactionWithMetadata Node

This contains a Transaction with Metadata describing how the LedgerEntry nodes were altered. It has the most complex structure of all nodes. A TransactionWithMetadata node is never reused between ledgers. VL is a variable length marker. 

Node: 	Complex encoding of Transaction
Index:	SHA512Half of HP_TRANSACTION_ID:Node
Hash:	SHA512Half of HP_TRANSACTION_NODE:VL:Node:VL:Metadata:Index

Key:	Hash
Value:	LedgerSequence:LedgerSequence:NT_TRANSACTION_NODE:HP_TRANSACTION_NODE:VL:Node:VL:Metadata:Index

LedgerEntry Node

This contains the state of an account after a transaction has been applied. Ledger Entry nodes may be reused between ledgers. 

Node:	Complex encoding of LedgerEntry
Index:	SHA512Half of namespace and a type-specific rule
Hash:	SHA512Half of HP_LEAF_NODE:Node:Index

Key:	Hash
Value:	LedgerSequence:LedgerSequence:NT_ACCOUNT_NODE:HP_LEAF_NODE:Node:Index

type Transfer 

type Transfer struct {
	Source             Account
	Destination        Account
	SourceBalance      Amount
	DestinationBalance Amount
	Change             Value
	TransitFee         *Value // Applies to all transfers except XRP -> XRP
	QualityIn          *Value // Applies to IOU -> IOU transfers
	QualityOut         *Value // Applies to IOU -> IOU transfers
}

Transfer is a directional representation of a RippleState or AccountRoot balance change. Payments and OfferCreates lead to the creation of zero or more Transfers. 

TransitFee is earned by the Issuer
QualityIn and QualityOut are earned by the Liquidity Provider and can be negative.

Four scenarios:

  1. XRP -> XRP
  2. XRP -> IOU/Issuer Requires an orderbook
  3. IOU/Issuer -> XRP Requires an orderbook
  4. IOU/IssuerA <-> IOU/IssuerB Also known as Rippling, requires an account which trusts both currency/issuer pairs

type Value 

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

Value is the numeric type in Ripple. It can store numbers in two different representations: native and non-native. Non-native numbers are stored as a mantissa (Num) in the range [1e15,1e16) plus an exponent (Offset) in the range [-96,80]. Native values are stored as an integer number of "drips" each representing 1/1000000. Throughout the library, native values are interpreted as drips unless otherwise specified.

func NewNativeValue 

func NewNativeValue(n int64) (*Value, error)

NewNativeValue returns a Value with n drops. If the value is impossible an error is returned.

func NewNonNativeValue 

func NewNonNativeValue(n int64, offset int64) (*Value, error)

NewNonNativeValue returns a Value of n*10^offset.

func NewValue 

func NewValue(s string, native bool) (*Value, error)

NewValue accepts a string representation of a value and a flag to indicate if it should be stored as native. If the native flag is set AND a decimal is used, the number is interpreted as XRP. If no decimal is used, it is interpreted as drips.

func (Value) Abs 

func (v Value) Abs() *Value

Abs returns a copy of v with a positive sign.

func (Value) Add 

func (a Value) Add(b Value) (*Value, error)

Add adds a to b and returns the sum as a new Value.

Example 
v1, _ := NewValue("100", false)
v2, _ := NewValue("200.199", false)
sum, _ := v1.Add(*v2)
fmt.Println(v1.String())
fmt.Println(v2.String())
fmt.Println(sum.String())

Output:

100
200.199
300.199

func (*Value) Bytes 

func (v *Value) Bytes() []byte

func (Value) Clone 

func (v Value) Clone() *Value

Clone returns a Value which is a copy of v.

func (Value) Compare 

func (a Value) Compare(b Value) int

Compare returns an integer comparing two Values. The result will be 0 if a==b, -1 if a < b, and +1 if a > b.

func (Value) Divide 

func (num Value) Divide(den Value) (*Value, error)

func (Value) Equals 

func (a Value) Equals(b Value) bool

func (Value) Float 

func (v Value) Float() float64

func (Value) IsNegative 

func (v Value) IsNegative() bool

func (Value) IsZero 

func (v Value) IsZero() bool

func (Value) Less 

func (a Value) Less(b Value) bool

Less compares values and returns true if a is less than b.

func (*Value) Marshal 

func (v *Value) Marshal(w io.Writer) error

func (Value) MarshalBinary 

func (v Value) MarshalBinary() ([]byte, error)

func (*Value) MarshalText 

func (v *Value) MarshalText() ([]byte, error)

func (Value) Multiply 

func (a Value) Multiply(b Value) (*Value, error)

func (Value) Native 

func (v Value) Native() (*Value, error)

Native returns a clone of the value in native format.

func (Value) Negate 

func (v Value) Negate() *Value

Negate returns a new Value with the opposite sign of v.

func (Value) NonNative 

func (v Value) NonNative() (*Value, error)

NonNative returns a clone of the value in non-native format.

func (Value) Rat 

func (v Value) Rat() *big.Rat

Rat returns the value as a big.Rat.

func (Value) Ratio 

func (a Value) Ratio(b Value) (*Value, error)

Ratio returns the ratio a/b. XRP are interpreted at face value rather than drips. The result of Ratio is always a non-native Value for additional precision.

func (Value) String 

func (v Value) String() string

String returns the Value as a string for human consumption. Native values are represented as decimal XRP rather than drips.

func (Value) Subtract 

func (a Value) Subtract(b Value) (*Value, error)

func (*Value) Unmarshal 

func (v *Value) Unmarshal(r Reader) error

func (*Value) UnmarshalBinary 

func (v *Value) UnmarshalBinary(b []byte) error
