Types

type AccessNodeConfig

type AccessNodeConfig struct {
	ExecutionNodeAddress string // deprecated
	HistoricalAccessRPCs []access.AccessAPIClient

	PublicNetworkConfig PublicNetworkConfig
	// contains filtered or unexported fields
}

AccessNodeConfig defines all the user defined parameters required to bootstrap an access node For a node running as a standalone process, the config fields will be populated from the command line params, while for a node running as a library, the config fields are expected to be initialized by the caller.

func DefaultAccessNodeConfig

func DefaultAccessNodeConfig() *AccessNodeConfig

DefaultAccessNodeConfig defines all the default values for the AccessNodeConfig

type FlowAccessNodeBuilder

type FlowAccessNodeBuilder struct {
	*cmd.FlowNodeBuilder
	*AccessNodeConfig
