func AllNil added in v0.3.1

func AllNil(a ...interface{}) bool

AllNil returns a bool whether All of the variadic inputs is nil if no inputs are passed, it defaults to true

func AllZero added in v0.3.1

func AllZero(a ...int) bool

AllZero returns a bool whether All of the variadic inputs is zero if no inputs are passed, it defaults to true

func Any added in v0.4.0

func Any(a ...bool) bool

Any returns a bool indicating whether any of the given bools are true

func AnyEmpty added in v0.3.1

func AnyEmpty(a ...string) bool

AnyEmpty returns a bool whether any of the variadic inputs is an "empty" string. see rstrings::IsEmpty for empty-checking logic if no inputs are passed, it defaults to false

EmptyOr is a coalescence operator similar to the python style "x = x or y", used to choose the first non-empty string

func First added in v0.3.1

func First(i ...interface{}) interface{}

First is a coalescing function to return the first non-type-default argument in the variadic arg list see IsDefaultValue for the default checking implementation

func IsDefaultValue added in v0.3.1

func IsDefaultValue(x interface{}) bool

IsDefaultValue returns whether the given interface is the default for its kind i.e. IsDefaultValue(1) -> false IsDefaultValue("") -> true

func NilOr

func NilOr(a, b interface{}) interface{}

NilOr is a coalescence operator similar to the python style "x = x or y", used to choose the first non-nil variable

func ZeroOr

func ZeroOr(a, b int) int

ZeroOr is a coalescence operator similar to the python style "x = x or y", used to choose the first nonzero integer
