Types

type Client

type Client struct {
	// Identifier is the human readable identifier for the instance.
	Identifier string

	// IAAddresses are the IP address:port combinations of Issuing Authority Servers.
	IAAddresses []string

	// UseGRPC specifies whether to use gRPC for sending server requests or TCP sockets.
	UseGRPC bool

	// IAAddresses are the gRPC IP address:port combinations of Issuing Authority Servers.
	IAgRPCAddresses []string

	// MaxRequests defines maximum number of concurrent requests each client can make.
	// -1 indicates no limit
	MaxRequests int

	// Threshold defines minimum number of signatures client needs to obtain. Default = len(IAAddresses).
	// 0 = no threshold
	Threshold int

	// MaximumAttributes specifies the maximum number of attributes the client will want to have signed.
	MaximumAttributes int
}

Client is the Coconut Client configuration.

type Config

type Config struct {
	Client  *Client
	Nym     *Nym
	Logging *Logging

	Debug *Debug
}

Config is the top level Coconut Client configuration.

func LoadBinary

func LoadBinary(b []byte) (*Config, error)

LoadBinary loads, parses and validates the provided buffer b (as a config) and returns the Config.

func LoadFile

func LoadFile(f string) (*Config, error)

LoadFile loads, parses and validates the provided file and returns the Config.

type Debug

type Debug struct {
	// NumJobWorkers specifies the number of worker instances to use for jobpacket processing.
	NumJobWorkers int

	// ConnectTimeout specifies the maximum time a connection can take to establish a TCP/IP connection in milliseconds.
	ConnectTimeout int

	// RequestTimeout specifies the maximum time a client is going to wait for its request to resolve.
	RequestTimeout int

	// RegenerateKeys specifies whether to generate new Coconut-specific ElGamal keypair and overwrite existing files.
	RegenerateKeys bool

	// NumberOfLookUpRetries specifies maximum number of retries to call issuer to look up the credentials.
	NumberOfLookUpRetries int

	// LookUpBackoff specifies the backoff duration after failing to look up credential
	// (assuming it was due to not being processed yet).
	LookUpBackoff int
}

Debug is the Coconut Client debug configuration.

type Logging

type Logging struct {
	// Disable disables logging entirely.
	Disable bool

	// File specifies the log file, if omitted stdout will be used.
	File string

	// Level specifies the log level.
	Level string
}

Logging is the Coconut Client logging configuration.

type Nym

type Nym struct {
	// NymContract defined address of the ERC20 token Nym contract. It is expected to be provided in hex format.
	NymContract ethcommon.Address

	// PipeAccount defines address of Ethereum account that pipes Nym ERC20 into Nym Tendermint coins.
	// It is expected to be provided in hex format.
	PipeAccount ethcommon.Address

	// AccountKeysFile specifies the file containing keys used for the accounts on the Nym Blockchain.
	AccountKeysFile string

	// BlockchainNodeAddresses specifies addresses of blockchain nodes
	// to which the client should send all relevant requests.
	// Note that only a single request will ever be sent, but multiple addresses are provided in case
	// the particular node was unavailable.
	BlockchainNodeAddresses []string

	// EthereumNodeAddresses specifies addresses of Ethereum nodes
	// to which the client should send all relevant requests.
	// Note that only a single request will ever be sent, but multiple addresses are provided in case
	// the particular node was unavailable. (TODO: implement this functionality)
	EthereumNodeAddresses []string
}

Nym defines Nym-specific configuration options.
