Variables

var (
	// ErrAllIPLookuppersFailed indicates that we failed with looking
	// up the probe IP for with all the lookuppers that we tried.
	ErrAllIPLookuppersFailed = errors.New("all IP lookuppers failed")

	// string that actually isn't a valid IP address.
	ErrInvalidIPAddress = errors.New("lookupper did not return a valid IP")
)

Types

type Config

type Config struct {
	// Resolver is the resolver we should use when
	// making requests for discovering the IP. When
	// this field is not set, we use the stdlib.
	Resolver model.Resolver

	// Logger is the logger to use. If not set, then we will
	// use a logger that discards all messages.
	Logger model.Logger

	// UserAgent is the user agent to use. If not set, then
	// we will use a default user agent.
	UserAgent string
}

Config contains configuration for a geolocate Task.

type Results

type Results struct {
	// ASN is the autonomous system number.
	ASN uint

	// CountryCode is the country code.
	CountryCode string

	// NetworkName is the network name.
	NetworkName string

	// IP is the probe IP.
	ProbeIP string

	// ResolverASN is the resolver ASN.
	ResolverASN uint

	// ResolverIP is the resolver IP.
	ResolverIP string

	// ResolverNetworkName is the resolver network name.
	ResolverNetworkName string
	// contains filtered or unexported fields
}

Results contains geolocate results.

func (*Results) ASNString

func (r *Results) ASNString() string

ASNString returns the ASN as a string.

type Task

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

Task performs a geolocation. You must create a new instance of Task using the NewTask factory.

func NewTask

func NewTask(config Config) *Task

NewTask creates a new instance of Task from config.

func (Task) Run

func (op Task) Run(ctx context.Context) (*Results, error)

Run runs the task.
