Functions

func ToBool

func ToBool(v Bool) bool

ToBool returns its argument as a bool. It panics if its argument is nil or not a bool.

func ToFloat64

func ToFloat64(v Float64) float64

ToFloat64 returns its argument as a float64. It panics if its argument is nil or not a float64.

func ToInt

func ToInt(v Int) int

ToInt returns its argument as an int. It panics if its argument is nil or not an int.

func ToString

func ToString(v String) string

ToString returns its argument as a string. It panics if its argument is nil or not a string.

func ToUint

func ToUint(v Uint) uint

ToUint returns its argument as a uint. It panics if its argument is nil or not a uint.
