func DefaultConfig added in v0.4.0

func DefaultConfig() *Config

DefaultConfig returns the default configuration

func (*Config) Copy added in v0.3.0

func (c *Config) Copy() *Config

func (*Config) Read

func (c *Config) Read(id string) string

Read returns the specified configuration value or "".

func (*Config) ReadBool added in v0.2.0

func (c *Config) ReadBool(id string) (bool, error)

ReadBool parses the specified option as a boolean.

func (*Config) ReadBoolDefault added in v0.2.0

func (c *Config) ReadBoolDefault(id string, defaultValue bool) bool

ReadBoolDefault tries to parse the specified option as a boolean. If there is an error in parsing, the default option is returned.

func (*Config) ReadDefault

func (c *Config) ReadDefault(id string, defaultValue string) string

ReadDefault returns the specified configuration value, or the specified default value if none is set.

func (*Config) ReadStringListToMap added in v0.2.1

func (c *Config) ReadStringListToMap(key string) map[string]struct{}

ReadStringListToMap tries to parse the specified option as a comma separated list. If there is an error in parsing, an empty list is returned.

func (*Config) ReadStringListToMapDefault added in v0.3.2

func (c *Config) ReadStringListToMapDefault(key, defaultValue string) map[string]struct{}

ReadStringListToMap tries to parse the specified option as a comma separated list. If there is an error in parsing, an empty list is returned.

func (*Config) TLSConfiguration added in v0.5.0

func (c *Config) TLSConfiguration() *tlsutil.Config

TLSConfig returns a TLSUtil Config based on the client configuration

type RPCHandler

type RPCHandler interface {
	RPC(method string, args interface{}, reply interface{}) error
}

RPCHandler can be provided to the Client if there is a local server to avoid going over the network. If not provided, the Client will maintain a connection pool to the servers
