Enum ScalarType 

pub enum ScalarType {
    Double,
    Float,
    Int64,
    Uint64,
    Int32,
    Fixed64,
    Fixed32,
    Bool,
    String,
    Bytes,
    Uint32,
    Sfixed32,
    Sfixed64,
    Sint32,
    Sint64,
}

Protobuf scalar field types.

This is field_descriptor_proto::Type minus TYPE_MESSAGE, TYPE_GROUP, and TYPE_ENUM — those get dedicated SingularKind variants instead of being lumped in with scalars.

Implementations

impl ScalarType

pub fn from_proto(ty: ProtoType) -> Option<Self>

Convert a raw proto Type to a ScalarType.

Returns None for TYPE_MESSAGE, TYPE_GROUP, and TYPE_ENUM, which are not scalar.

pub fn is_valid_map_key(self) -> bool

Whether this scalar is valid as a protobuf map key.

Per the protobuf spec: integral types, bool, and string. Not floats, not bytes.

Trait Implementations

impl Clone for ScalarType

fn clone(&self) -> ScalarType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ScalarType

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

Formats the value using the given formatter.

impl Hash for ScalarType

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 ScalarType

fn eq(&self, other: &ScalarType) -> 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.
