Types

type Config

type Config struct {
	Plugins            map[int]interface{}             `ymal:"plugins"`
	Network            p2p.Config                      `yaml:"network"`
	Chain              blockchain.Config               `yaml:"chain"`
	ActPool            actpool.Config                  `yaml:"actPool"`

	DB                 db.Config                       `yaml:"db"`
	Indexer            blockindex.Config               `yaml:"indexer"`

	NodeInfo           nodeinfo.Config                 `yaml:"nodeinfo"`
}

Config is the root config struct, each package's config should be put as its sub struct

func New

func New(configPaths []string, _plugins []string, validates ...Validate) (Config, error)

New creates a config instance. It first loads the default configs. If the config path is not empty, it will read from the file and override the default configs. By default, it will apply all validation functions. To bypass validation, use DoNotValidate instead.

func NewSub

func NewSub(configPaths []string, validates ...Validate) (Config, error)

NewSub create config for sub chain.

type System

type System struct {
	// Active is the status of the node. True means active and false means stand-by
	Active            bool          `yaml:"active"`
	HeartbeatInterval time.Duration `yaml:"heartbeatInterval"`
	// HTTPProfilingPort is the port number to access golang performance profiling data of a blockchain node. It is
	// 0 by default, meaning performance profiling has been disabled
	HTTPAdminPort         int           `yaml:"httpAdminPort"`
	HTTPStatsPort         int           `yaml:"httpStatsPort"`
	StartSubChainInterval time.Duration `yaml:"startSubChainInterval"`
	SystemLogDBPath       string        `yaml:"systemLogDBPath"`
	MptrieLogPath         string        `yaml:"mptrieLogPath"`
}

System is the system config

type Validate

type Validate func(Config) error

Validate is the interface of validating the config
