NullValue
is a singleton enumeration to represent the null value for the
Value
type union.
The JSON representation for NullValue
is JSON null
.
Variants
NullValue
Null value.
Methods
impl NullValue
[src]
pub fn is_valid(value: i32) -> bool
[src]
Returns true
if value
is a variant of NullValue
.
pub fn from_i32(value: i32) -> Option<NullValue>
[src]
Converts an i32
to a NullValue
, or None
if value
is not a valid variant.
