Enum SingularKind 

pub enum SingularKind {
    Scalar(ScalarType),
    Enum(EnumIndex),
    Message(MessageIndex),
}

The element kind of a singular field, list element, or map value.

Separating this from FieldKind makes List(List(...)) and Map { value: Map {..} } unrepresentable — protobuf does not allow nested repeated or map-of-map. It also keeps FieldKind Copy.

Variants

Scalar(ScalarType)

A scalar value.

Enum(EnumIndex)

An enum value, referencing an enum in the pool.

Message(MessageIndex)

A message value, referencing a message in the pool.

Trait Implementations

impl Clone for SingularKind

fn clone(&self) -> SingularKind

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SingularKind

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for SingularKind

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for SingularKind

fn eq(&self, other: &SingularKind) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
