fn values() -> &'static [Self]

Get all enum values for enum type.

fn enum_descriptor_static() -> &'static EnumDescriptor

Get enum descriptor by type.

fn descriptor(&self) -> &'static EnumValueDescriptor

Get enum value descriptor.

fn enum_descriptor(&self) -> &'static EnumDescriptor

Get enum descriptor.

fn as_ref(&self) -> ProtobufValueRef

As ref

fn as_any(&self) -> &dyn Any

Convert to Any

fn is_non_zero(&self) -> bool

Is value non-zero?

fn as_ref_copy(&self) -> ProtobufValueRef<'static>

Return ProtobufValueRef if self is Copy.

impl Default for Field_Cardinality

fn default() -> Self

Returns the "default value" for a type.
