func GetFunctionName ¶
GetFunctionName returns a name of function
func GetIPAddress ¶
GetIPAddress пытается получить IP адрес из заголовков HTTP возвращает соотв-ю строку, или "0.0.0.0"
func GetSelfPath ¶
GetSelfPath returns a path to the caller executable
func IsEmptyDir ¶ added in v1.0.6
IsEmptyDir returns true if the path specified is an empty directory
func IsInDocker ¶ added in v1.0.7
func IsInDocker() bool
IsInDocker returns whether execution is going inside a Docker container
func IsInGitlab ¶ added in v1.0.8
func IsInGitlab() bool
IsInGitlab returns true if we are in Gitlab
func IsNil ¶
func IsNil(obj interface{}) bool
IsNil returns true if obj is nil or contains empty value, otherwise returns false
func MarshalUnmarshalJSON ¶ added in v1.0.2
func MarshalUnmarshalJSON(data, out interface{}) error
MarshalUnmarshalJSON marshals data to JSON and unmarshal it to out. Useful to convert interface{} to something more concrete via JSON
func MustMarshalJSON ¶ added in v1.0.12
func MustMarshalJSON(data interface{}) []byte
MustMarshalJSON works as json.Marshal, but panics on error
func MustMarshalUnmarshalJSON ¶ added in v1.0.5
func MustMarshalUnmarshalJSON(data, out interface{})
MustMarshalUnmarshalJSON works like MarshalUnmarshalJSON but panic on error
func MustSelfPath ¶
func MustSelfPath() string
MustSelfPath returns path to this application executable, it panic at error
func NewFileUploadRequest ¶
func NewFileUploadRequest(req FileUploadRequest) (*http.Request, error)
NewFileUploadRequest creates a new file upload HTTP request with optional extra params
func RemoveDuplicates ¶
RemoveDuplicates returns a slice with duplicates removed. It omits NaN values and returns true in second parameter if a NaN value were found.
func Round ¶
Round округляет значение val. Возвращает округлённое значение. Параметр roundOn задаёт значение разряда, по которому определяется вид округления - в большую или в меньшую сторону. Параметр places определяет количество знаков после десятичной точки, в случае, если он положителен, до целых - если 0. Может быть отрицательным, в этом случае, например, при -1 округление выполняется до десятков. Примеры: Round(2.34, .5, 1) возвращает 2.3 Round(2.37, .5, 1) возвращает 2.4 Round(2.37, .5, 0) возвращает 2.0 Round(2.77, .5, 0) возвращает 3.0
func SliceContains ¶
func SliceContains(needle interface{}, haystack interface{}) bool
SliceContains checks for value of needle in slice haystack haystack's underlying type should be a slice, if not, the function panics
func SliceIntersects ¶ added in v1.0.10
func SliceIntersects(a, b interface{}) bool
SliceIntersects returns whether two slices intersects
func StringSliceSubstract ¶ added in v1.0.9

func StringToStringSlice ¶
StringToStringSlice converts a string values separated by sep to slice of string elements empty elements are ignored
func StringToUint ¶
StringToUint interpretes string as a value of type uint
func StringToUintSlice ¶
StringToUintSlice converts a string values separated by sep to slice of uint elements It returns an error if any element can't be converted to uint If a converted element is less than min, it will not be added empty elements are ignored
func SubstringBetween ¶
SubstringBetween returns a substring between substrs l and r from source string s
func ToLowerFirstRune ¶
ToLowerFirstRune returns string s with first rune converted to it's lowercase form
func Try ¶
func Try(actionFunc func() error, n int, delay time.Duration, conditionFunc func(e error) bool) (int, error)
Try tries n times to call an actionFunc() until conditionFunc() returns true actionFunc is a func returning error n is a number of times to try to call actionFunc() delay is a delay between calls actionFunc() conditionFunc is a func accepting error, if it returns true, Try will try again Try returns a number of attempts
