Functions

func From

func From(typ interface{}) interface{}

From(*T) -> func(t T) T {return t}

func FullNodeHandler

func FullNodeHandler(a v1api.FullNode, permissioned bool, opts ...jsonrpc.ServerOption) (http.Handler, error)

FullNodeHandler returns a full node handler, to be mounted as-is on the server.

func IsType

func IsType(t repo.RepoType) func(s *Settings) bool

func MinerHandler

func MinerHandler(a api.StorageMiner, permissioned bool) (http.Handler, error)

MinerHandler returns a miner handler, to be mounted as-is on the server.

func MonitorShutdown

func MonitorShutdown(triggerCh <-chan struct{}, handlers ...ShutdownHandler) <-chan struct{}

MonitorShutdown manages shutdown requests, by watching signals and invoking the supplied handlers in order.

It watches SIGTERM and SIGINT OS signals, as well as the trigger channel. When any of them fire, it calls the supplied handlers in order. If any of them errors, it merely logs the error.

Once the shutdown has completed, it closes the returned channel. The caller can watch this channel

func WithEnableLibp2pNode

func WithEnableLibp2pNode(enable bool) func(s *Settings) error

func WithInvokesKey

func WithInvokesKey(i invoke, resApi interface{}) func(s *Settings) error

func WithRepoType

func WithRepoType(repoType repo.RepoType) func(s *Settings) error

Types

type FullOption

type FullOption = Option

func Lite

func Lite(enable bool) FullOption

type Option

type Option func(*Settings) error

Option is a functional option which can be used with the New function to change how the node is constructed

Options are applied in sequence

func ApplyIf

func ApplyIf(check func(s *Settings) bool, opts ...Option) Option

func Base

func Base() Option

func ConfigCommon

func ConfigCommon(cfg *config.Common, enableLibp2pNode bool) Option

Config sets up constructors based on the provided Config

func ConfigFullNode

func ConfigFullNode(c interface{}) Option

func ConfigStorageMiner

func ConfigStorageMiner(c interface{}) Option

func Error

func Error(err error) Option

Error is a special option which returns an error when applied

func FullAPI

func FullAPI(out *api.FullNode, fopts ...FullOption) Option

func If

func If(b bool, opts ...Option) Option

func MockHost

func MockHost(mn mocknet.Mocknet) Option

func Options

func Options(opts ...Option) Option

Options groups multiple options into one

func Override

func Override(typ, constructor interface{}) Option

Override option changes constructor for a given type

func Repo

func Repo(r repo.Repo) Option

func StorageMiner

func StorageMiner(out *api.StorageMiner, subsystemsCfg config.MinerSubsystemConfig) Option

func Test

func Test() Option

func Unset

func Unset(typ interface{}) Option

type Settings

type Settings struct {
	Base   bool // Base option applied
	Config bool // Config option applied
	Lite   bool // Start node in "lite" mode
	// contains filtered or unexported fields
}

type ShutdownHandler

type ShutdownHandler struct {
	Component string
	StopFunc  StopFunc
}

type StopFunc

type StopFunc func(context.Context) error

func New

func New(ctx context.Context, opts ...Option) (StopFunc, error)

New builds and starts new Filecoin node

func ServeRPC

func ServeRPC(h http.Handler, id string, addr multiaddr.Multiaddr) (StopFunc, error)

ServeRPC serves an HTTP handler over the supplied listen multiaddr.

This function spawns a goroutine to run the server, and returns immediately. It returns the stop function to be called to terminate the endpoint.

The supplied ID is used in tracing, by inserting a tag in the context.
