type AppPath struct {
	Entry *sciond.PathReplyEntry
}

AppPath contains a SCIOND path entry.

func (ap *AppPath) Copy() *AppPath

func (ap *AppPath) Key() PathKey

Key returns a unique PathKey that can be used for map indexing.

type AppPathSet map[PathKey]*AppPath

AppPathSet represents a set of SCIOND path entries, keyed by AppPath.Key().

func NewAppPathSet(reply *sciond.PathReply) AppPathSet

NewAppPathSet creates a new set of paths from a SCIOND path reply.

func (aps AppPathSet) Add(entry *sciond.PathReplyEntry) *AppPath

Add converts the SCIOND path entry to an AppPath and adds it to the set.

func (aps AppPathSet) Copy() AppPathSet

func (aps AppPathSet) GetAppPath(pref PathKey) *AppPath

GetAppPath returns an AppPath from the set. It first tries to find a path with key pref; if one cannot be found, an arbitrary one is returned.

func (aps AppPathSet) String() string

type PathKey string

Helper type for pretty printing of maps using paths as keys.

func (pk PathKey) String() string
