Functions

func AsBool

func AsBool(v any) bool

some helper functions related to numbers

func AsFloat

func AsFloat(v any) (float64, bool)

func AsInt

func AsInt(v any) (int64, bool)

func AsNumber

func AsNumber(v any) (any, bool)

func AsString

func AsString(v any) (string, bool)

func AsUint

func AsUint(v any) (uint64, bool)

func Assign

func Assign(dst, src any) error

func BaseType

func BaseType(v any) any

BaseType attempts to convert v into its base type, that is if v is a type that is defined as `type foo string`, a simple string will be returned.
