Functions

func Get

func Get(ctx context.Context, url string, headers map[string]string, timeout time.Duration) (string, error)

Get is a helper function to make a GET request to the specified URL and return the response body as a string.

Shutdown invokes fx.Shutdowner and logs error if any.

func SliceContains

func SliceContains(a []string, x string) bool

SliceContains tells whether a contains x.

func SliceFind

func SliceFind(a []string, x string) int

SliceFind returns the smallest index i at which x == a[i], or len(a) if there is no such index.

func SliceToMap

func SliceToMap(a []string) map[string]bool

SliceToMap converts a slice of string to a map[string]bool.
