Types

type API

type API interface {
	DataAPI
	ConstructionAPI
}

API defines the exposed APIs if the service is online

type BlockResponse

type BlockResponse struct {
	Block                *types.BlockIdentifier
	ParentBlock          *types.BlockIdentifier
	MillisecondTimestamp int64
	TxCount              int64
}

type BlockTransactionsResponse

type BlockTransactionsResponse struct {
	BlockResponse
	Transactions []*types.Transaction
}

type Client

type Client interface {
	// Bootstrap Needed if the client needs to perform some action before connecting.
	Bootstrap() error
	// Ready checks if the servicer constraints for queries are satisfied
	// for example the node might still not be ready, it's useful in process
	// when the rosetta instance might come up before the node itself
	// the servicer must return nil if the node is ready
	Ready() error

	// Balances fetches the balance of the given address
	// if height is not nil, then the balance will be displayed
	// at the provided height, otherwise last block balance will be returned
	Balances(ctx context.Context, addr string, height *int64) ([]*types.Amount, error)
	// BlockByHash gets a block and its transaction at the provided height
	BlockByHash(ctx context.Context, hash string) (BlockResponse, error)
	// BlockByHeight gets a block given its height, if height is nil then last block is returned
	BlockByHeight(ctx context.Context, height *int64) (BlockResponse, error)
	// BlockTransactionsByHash gets the block, parent block and transactions
	// given the block hash.
	BlockTransactionsByHash(ctx context.Context, hash string) (BlockTransactionsResponse, error)
	// BlockTransactionsByHeight gets the block, parent block and transactions
	// given the block hash.
	BlockTransactionsByHeight(ctx context.Context, height *int64) (BlockTransactionsResponse, error)
	// GetTx gets a transaction given its hash
	GetTx(ctx context.Context, hash string) (*types.Transaction, error)
	// GetUnconfirmedTx gets an unconfirmed Tx given its hash
	// NOTE(fdymylja): NOT IMPLEMENTED YET!
	GetUnconfirmedTx(ctx context.Context, hash string) (*types.Transaction, error)
	// Mempool returns the list of the current non confirmed transactions
	Mempool(ctx context.Context) ([]*types.TransactionIdentifier, error)
	// Peers gets the peers currently connected to the node
	Peers(ctx context.Context) ([]*types.Peer, error)
	// Status returns the node status, such as sync data, version etc
	Status(ctx context.Context) (*types.SyncStatus, error)

	// PostTx posts txBytes to the node and returns the transaction identifier plus metadata related
	// to the transaction itself.
	PostTx(txBytes []byte) (res *types.TransactionIdentifier, meta map[string]interface{}, err error)
	// ConstructionMetadataFromOptions builds metadata map from an option map
	ConstructionMetadataFromOptions(ctx context.Context, options map[string]interface{}) (meta map[string]interface{}, err error)
	OfflineClient
}

Client defines the API the client implementation should provide.

type ConstructionAPI

type ConstructionAPI interface {
	ConstructionOnlineAPI
	ConstructionOfflineAPI
}

ConstructionAPI defines the full construction API with the online and offline endpoints

type ConstructionOnlineAPI

type ConstructionOnlineAPI interface {
	ConstructionMetadata(
		context.Context,
		*types.ConstructionMetadataRequest,
	) (*types.ConstructionMetadataResponse, *types.Error)
	ConstructionSubmit(
		context.Context,
		*types.ConstructionSubmitRequest,
	) (*types.TransactionIdentifierResponse, *types.Error)
}

ConstructionOnlineAPI defines the construction methods allowed in an online implementation

type DataAPI

DataAPI defines the full data API implementation

type NetworkInformationProvider

type NetworkInformationProvider interface {
	// SupportedOperations lists the operations supported by the implementation
	SupportedOperations() []string
	// OperationStatuses returns the list of statuses supported by the implementation
	OperationStatuses() []*types.OperationStatus
	// Version returns the version of the node
	Version() string
}

NetworkInformationProvider defines the interface used to provide information regarding the network and the version of the cosmos sdk used

type OfflineClient

type OfflineClient interface {
	NetworkInformationProvider
	// SignedTx returns the signed transaction given the tx bytes (msgs) plus the signatures
	SignedTx(ctx context.Context, txBytes []byte, sigs []*types.Signature) (signedTxBytes []byte, err error)
	// TxOperationsAndSignersAccountIdentifiers returns the operations related to a transaction and the account
	// identifiers if the transaction is signed
	TxOperationsAndSignersAccountIdentifiers(signed bool, hexBytes []byte) (ops []*types.Operation, signers []*types.AccountIdentifier, err error)
	// ConstructionPayload returns the construction payload given the request
	ConstructionPayload(ctx context.Context, req *types.ConstructionPayloadsRequest) (resp *types.ConstructionPayloadsResponse, err error)
	// PreprocessOperationsToOptions returns the options given the preprocess operations
	PreprocessOperationsToOptions(ctx context.Context, req *types.ConstructionPreprocessRequest) (resp *types.ConstructionPreprocessResponse, err error)
	// AccountIdentifierFromPublicKey returns the account identifier given the public key
	AccountIdentifierFromPublicKey(pubKey *types.PublicKey) (*types.AccountIdentifier, error)
}

OfflineClient defines the functionalities supported without having access to the node
