}

A Protocol Buffers field type, i.e. FieldDescriptorProto.Type in descriptor.proto. The discriminants are the on-the-wire enum values.

Variants

Double = 1

double -> f64.

Float = 2

float -> f32.

Int64 = 3

int64 (varint) -> i64.

Uint64 = 4

uint64 (varint) -> u64.

Int32 = 5

int32 (varint) -> i32.

Fixed64 = 6

fixed64 (8 bytes) -> u64.

Fixed32 = 7

fixed32 (4 bytes) -> u32.

Bool = 8

bool -> boolean.

String = 9

string (UTF-8) -> XTypes string.

Group = 10

Deprecated proto2 group, mapped like a nested message.

Message = 11

Nested message -> nested struct (resolved from type_name).

Bytes = 12

bytes -> sequence<byte>.

Uint32 = 13

uint32 (varint) -> u32.

Enum = 14

enum -> XTypes enum (resolved from type_name).

Sfixed32 = 15

sfixed32 (4 bytes, signed) -> i32.

Sfixed64 = 16

sfixed64 (8 bytes, signed) -> i64.

Sint32 = 17

sint32 (zigzag varint) -> i32.

Sint64 = 18

sint64 (zigzag varint) -> i64.

Implementations

impl ProtoFieldType

pub fn from_wire(v: i32) -> Option<Self>

Decode the FieldDescriptorProto.Type enum value. Returns None for out-of-range values (a malformed or newer descriptor).

pub fn scalar_type_kind(self) -> Option<TypeKind>

The XTypes TypeKind for a directly-representable field type.

None for the field types that do not map to a single primitive:

• ProtoFieldType::Bytes -> sequence<byte> (a collection),
• ProtoFieldType::Message / ProtoFieldType::Group -> a nested struct (resolved from the descriptor’s type_name),
• ProtoFieldType::Enum -> an XTypes enum (resolved from type_name).

These are handled by the descriptor mapper (CP-A3), not here.
