Constants for the byte size of each Go numeric type.

Variables

var Kind = map[reflect.Kind]uint64{
	reflect.Int:        Int,
	reflect.Uint:       Uint,
	reflect.Uintptr:    Uintptr,
	reflect.Bool:       Bool,
	reflect.Int8:       Int8,
	reflect.Int16:      Int16,
	reflect.Int32:      Int32,
	reflect.Int64:      Int64,
	reflect.Uint8:      Uint8,
	reflect.Uint16:     Uint16,
	reflect.Uint32:     Uint32,
	reflect.Uint64:     Uint64,
	reflect.Float32:    Float32,
	reflect.Float64:    Float64,
	reflect.Complex64:  Complex64,
	reflect.Complex128: Complex128,
}

Kind maps each numeric reflect.Kind to the number of bytes it takes. Non-numeric kinds and aliases are not included.
