Types

type Parameter

type Parameter interface {
	// contains filtered or unexported methods
}

Parameter is the interface for service parameters.

func WithForkScheduleProvider

func WithForkScheduleProvider(provider eth2client.ForkScheduleProvider) Parameter

WithForkScheduleProvider sets the fork schedule provider.

WithLogLevel sets the log level for the module.

func WithSpecProvider

func WithSpecProvider(provider eth2client.SpecProvider) Parameter

WithSpecProvider sets the spec provider.

type Service

type Service struct {
	// contains filtered or unexported fields
}

Service provides chain time services.

func New

func New(ctx context.Context, params ...Parameter) (*Service, error)

New creates a new controller.
