Functions ¶

func NewExtendedContext ¶

func NewExtendedContext(refCtx context.Context,
	minLifetime time.Duration) (context.Context, context.CancelFunc)

NewExtendedContext returns a new _independent_ context that can extend past refCtx's lifetime, guaranteeing a minimum lifetime of minLifetime. If refCtx has a deadline, the newly created context will have a deadline equal to the maximum of refCtx's deadline and (minLifetime + currentTime). If refCtx does not have a deadline, the function panics.

Because the returned context is independent, calling refCtx's cancellation function will not result in the cancellation of the returned context.

Types ¶

type Fetcher ¶

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

func NewFetcher ¶

func NewFetcher(messenger infra.Messenger, pathDB pathdb.PathDB,
	trustStore infra.TrustStore, revCache revcache.RevCache, cfg sdconfig.Config,
	logger log.Logger) *Fetcher

func (*Fetcher) GetPaths ¶

func (f *Fetcher) GetPaths(ctx context.Context, req *sciond.PathReq,
	earlyReplyInterval time.Duration) (*sciond.PathReply, error)
