Functions

func BoostHandler 

func BoostHandler(a api.Boost, permissioned bool) (http.Handler, error)

BoostHandler returns a boost service handler, to be mounted as-is on the server.

func From 

func From(typ interface{}) interface{}

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

func FromVal added in v1.6.0 

func FromVal[T any](v T) func() T

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

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 BoostAPI 

func BoostAPI(out *api.Boost) Option

func ConfigBoost 

func ConfigBoost(cfg *config.Boost) Option

func ConfigCommon 

func ConfigCommon(cfg *config.Common) Option

Config sets up constructors based on the provided Config

func Error 

func Error(err error) Option

Error is a special option which returns an error when applied

func If 

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

func Unset 

func Unset(typ interface{}) Option

type Settings 

type Settings struct {
	Base   bool // Base option applied
	Config bool // Config option applied

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.
