Functions

func ApplyWithBackoff

func ApplyWithBackoff(f func() error) error

ApplyWithBackoff tries to apply the specified function using an exponential backoff algorithm. If the function eventually succeed nil is returned, otherwise the error returned by f.

func Contains

func Contains(list []string, s string) bool

Contains checks whether the specified string is contained in the given string slice. Returns true if it does, false otherwise

func IsBool

func IsBool(value interface{}, key string) error

IsBool checks if value stored at a given key is a bool.

func IsInt

func IsInt(value interface{}, key string) error

IsInt checks if values stored at a given key is an int.

func IsNotEmpty

func IsNotEmpty(value interface{}, key string) error

IsNotEmpty checks if value stored at given key is empty. if it is empty it returns an error.

func NameOfFunction

func NameOfFunction(pc uintptr) string

NameOfFunction gives name of the current function given program counter.

Types

type MultiError

type MultiError struct {
	Errors []error
}

MultiError is a collection of errors.

func (*MultiError) Collect

func (m *MultiError) Collect(err error)

Collect appends an error to this MultiError.

func (*MultiError) Empty

func (m *MultiError) Empty() bool

Empty returns true if current MuiltiError is empty, false otherwise.

func (MultiError) ToError

func (m MultiError) ToError() error

ToError returns a single error made up of all errors in this MultiError.
