Functions

func AcquirePeeringConfigHotReload

func AcquirePeeringConfigHotReload() bool

func AllowPeeringConfigHotReload

func AllowPeeringConfigHotReload()

func DenyPeeringConfigHotReload

func DenyPeeringConfigHotReload()

func FetchConfig

func FetchConfig() error

FetchConfig fetches config values from a dir defined via CLI flag --config-dir (or the current working dir if not set).

It automatically reads in a single config file starting with "config" (can be changed via the --config CLI flag) and ending with: .json, .toml, .yaml or .yml (in this sequence).

func HideConfigFlags

func HideConfigFlags()

HideConfigFlags hides all non essential flags from the help/usage text.

func LoadHashFromEnvironment

func LoadHashFromEnvironment(name string, length ...int) (trinary.Hash, error)

LoadHashFromEnvironment loads a hash from the given environment variable.

func PrintConfig

func PrintConfig(ignoreSettingsAtPrint ...[]string)

Types

type PeerConfig

type PeerConfig struct {
	ID         string `json:"identity" mapstructure:"identity"`
	Alias      string `json:"alias" mapstructure:"alias"`
	PreferIPv6 bool   `json:"preferIPv6" mapstructure:"preferIPv6"`
}

PeerConfig holds the initial information about peers.
