Functions

func AccountString added in v0.1.7 

func AccountString(account *AccountIdentifier) string

AccountString returns a human-readable representation of a *types.AccountIdentifier.

func AddValues added in v0.1.7 

func AddValues(
	a string,
	b string,
) (string, error)

AddValues adds string amounts using big.Int.

func CurrencyString added in v0.1.7 

func CurrencyString(currency *Currency) string

CurrencyString returns a human-readable representation of a *types.Currency.

func Hash added in v0.1.7 

func Hash(i interface{}) string

Hash returns a deterministic hash for any interface. This works because Golang's JSON marshaler sorts all map keys, recursively. Source: https://golang.org/pkg/encoding/json/#Marshal Inspiration: https://github.com/onsi/gomega/blob/c0be49994280db30b6b68390f67126d773bc5558/matchers/match_json_matcher.go#L16

It is important to note that any interface that is a slice or contains slices will not be equal if the slice ordering is different.

func MarshalMap added in v0.1.8 

func MarshalMap(input interface{}) (map[string]interface{}, error)

MarshalMap attempts to marshal an interface into a map[string]interface{}. This function is used similarly to json.Marshal.

Types

type AccountBalanceRequest 

type AccountBalanceRequest struct {
	NetworkIdentifier *NetworkIdentifier      `json:"network_identifier"`
	AccountIdentifier *AccountIdentifier      `json:"account_identifier"`
	BlockIdentifier   *PartialBlockIdentifier `json:"block_identifier,omitempty"`
}

AccountBalanceRequest An AccountBalanceRequest is utilized to make a balance request on the /account/balance endpoint. If the block_identifier is populated, a historical balance query should be performed.

type AccountBalanceResponse 

type AccountBalanceResponse struct {
	BlockIdentifier *BlockIdentifier `json:"block_identifier"`
	// A single account may have a balance in multiple currencies.
	Balances []*Amount `json:"balances"`
	// Account-based blockchains that utilize a nonce or sequence number should include that number
	// in the metadata. This number could be unique to the identifier or global across the account
	// address.
	Metadata map[string]interface{} `json:"metadata,omitempty"`
}

AccountBalanceResponse An AccountBalanceResponse is returned on the /account/balance endpoint. If an account has a balance for each AccountIdentifier describing it (ex: an ERC-20 token balance on a few smart contracts), an account balance request must be made with each AccountIdentifier.

type AccountIdentifier 

type AccountIdentifier struct {
	// The address may be a cryptographic public key (or some encoding of it) or a provided
	// username.
	Address    string                `json:"address"`
	SubAccount *SubAccountIdentifier `json:"sub_account,omitempty"`
	// Blockchains that utilize a username model (where the address is not a derivative of a
	// cryptographic public key) should specify the public key(s) owned by the address in metadata.
	Metadata map[string]interface{} `json:"metadata,omitempty"`
}

AccountIdentifier The account_identifier uniquely identifies an account within a network. All fields in the account_identifier are utilized to determine this uniqueness (including the metadata field, if populated).

type Allow added in v0.1.2

	// that is not listed here will cause client validation to error.
	OperationTypes []string `json:"operation_types"`
	// All Errors that this implementation could return. Any error that is returned during parsing
	// that is not listed here will cause client validation to error.
	Errors []*Error `json:"errors"`
}

Allow Allow specifies supported Operation status, Operation types, and all possible error statuses. This Allow object is used by clients to validate the correctness of a Rosetta Server implementation. It is expected that these clients will error if they receive some response that contains any of the above information that is not specified here.

type Amount

	// Value of the transaction in atomic units represented as an arbitrary-sized signed integer.
	// For example, 1 BTC would be represented by a value of 100000000.
	Value    string                 `json:"value"`
	Currency *Currency              `json:"currency"`
	Metadata map[string]interface{} `json:"metadata,omitempty"`
}

Amount Amount is some Value of a Currency. It is considered invalid to specify a Value without a Currency.

type Block 

type Block struct {
	BlockIdentifier       *BlockIdentifier `json:"block_identifier"`
	ParentBlockIdentifier *BlockIdentifier `json:"parent_block_identifier"`

type BlockResponse 

type BlockResponse struct {
	Block *Block `json:"block"`
	// Some blockchains may require additional transactions to be fetched that weren't returned in
	// the block response (ex: block only returns transaction hashes). For blockchains with a lot of
	// transactions in each block, this can be very useful as consumers can concurrently fetch all
	// transactions returned.
	OtherTransactions []*TransactionIdentifier `json:"other_transactions,omitempty"`
}

BlockResponse A BlockResponse includes a fully-populated block or a partially-populated block with a list of other transactions to fetch (other_transactions).

type ConstructionMetadataRequest added in v0.1.2 

type ConstructionMetadataRequest struct {
	NetworkIdentifier *NetworkIdentifier `json:"network_identifier"`
	// Some blockchains require different metadata for different types of transaction construction
	// (ex: delegation versus a transfer). Instead of requiring a blockchain node to return all
	// possible types of metadata for construction (which may require multiple node fetches), the
	// client can populate an options object to limit the metadata returned to only the subset
	// required.
	Options map[string]interface{} `json:"options"`
}

ConstructionMetadataRequest A ConstructionMetadataRequest is utilized to get information required to construct a transaction. The Options object used to specify which metadata to return is left purposely unstructured to allow flexibility for implementers.

type Currency 

type Currency struct {
	// Canonical symbol associated with a currency.
	Symbol string `json:"symbol"`
	// Number of decimal places in the standard unit representation of the amount.  For example, BTC
	// has 8 decimals. Note that it is not possible to represent the value of some currency in
	// atomic units that is not base 10.
	Decimals int32 `json:"decimals"`
	// Any additional information related to the currency itself.  For example, it would be useful
	// to populate this object with the contract address of an ERC-20 token.
	Metadata map[string]interface{} `json:"metadata,omitempty"`
}

Currency Currency is composed of a canonical Symbol and Decimals. This Decimals value is used to convert an Amount.Value from atomic units (Satoshis) to standard units (Bitcoins).

type Error 

type Error struct {
	// Code is a network-specific error code. If desired, this code can be equivalent to an HTTP
	// status code.
	Code int32 `json:"code"`
	// Message is a network-specific error message.
	Message string `json:"message"`
	// An error is retriable if the same request may succeed if submitted again.
	Retriable bool `json:"retriable"`
}

type OperationIdentifier 

type OperationIdentifier struct {
	// The operation index is used to ensure each operation has a unique identifier within a
	// transaction.  To clarify, there may not be any notion of an operation index in the blockchain
	// being described.
	Index int64 `json:"index"`
	// Some blockchains specify an operation index that is essential for client use. For example,

	// Operation.Account. Some blockchains (like Bitcoin) only include successful operations in
	// blocks but other blockchains (like Ethereum) include unsuccessful operations that incur a
	// fee.  To reconcile the computed balance from the stream of Operations, it is critical to
	// understand which Operation.Status indicate an Operation is successful and should affect an
	// Account.
