Functions

func HarvesineDistance

func HarvesineDistance(coords1, coords2 GeoCoordinates) float64

HarvesineDistance finds the distance in KMs between two points on Earth. Formula converted to golang from https://www.movable-type.co.uk/scripts/latlong.html

Types

type GeoCoordinates

type GeoCoordinates struct {
	Lat  float64
	Long float64
}

GeoCoordinates represent a latitude and longitude on Earth.

func FindCoordsForPostcode

func FindCoordsForPostcode(zip string) (*GeoCoordinates, error)

FindCoordsForPostcode returns the geocoordinates for a zip code.

type HTTPGetter

type HTTPGetter interface {
	Get(url string) (resp *http.Response, err error)
}

HTTPGetter for mocking the HTTP client in tests.

type StringReadCloser

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

StringReadCloser implements ReadCloser and exposes a reader for strings.

func NewStringReadCloser

func NewStringReadCloser(s string) *StringReadCloser

NewStringReadCloser creates a new, initialized StringReadCloser.

func (*StringReadCloser) Close

func (src *StringReadCloser) Close() error

Close really does nothing except satify the ReadCloser interface.

func (*StringReadCloser) Read

func (src *StringReadCloser) Read(p []byte) (n int, err error)

Read reads data from the string.
