Protobuf supported field types

Variants

Int32(Span)

Protobuf int32

Remarks

Uses variable-length encoding. Inefficient for encoding negative numbers – if your field is likely to have negative values, use sint32 instead.

Int64(Span)

Protobuf int64

Remarks

Uses variable-length encoding. Inefficient for encoding negative numbers – if your field is likely to have negative values, use sint64 instead.

Uint32(Span)

Protobuf uint32

Remarks

Uses variable-length encoding.

Uint64(Span)

Protobuf uint64

Remarks

Uses variable-length encoding.

Sint32(Span)

Protobuf sint32

Remarks

Uses ZigZag variable-length encoding. Signed int value. These more efficiently encode negative numbers than regular int32s.

Sint64(Span)

Protobuf sint64

Remarks

Uses ZigZag variable-length encoding. Signed int value. These more efficiently encode negative numbers than regular int32s.

Bool(Span)

Protobuf bool

Fixed64(Span)

Protobuf fixed64

Remarks

Always eight bytes. More efficient than uint64 if values are often greater than 2^56.

Sfixed64(Span)

Protobuf sfixed64

Remarks

Always eight bytes.

Double(Span)

Protobuf double

String(Span)

Protobuf string

Remarks

A string must always contain UTF-8 encoded or 7-bit ASCII text.

Bytes(Span)

Protobuf bytes

Remarks

May contain any arbitrary sequence of bytes.

Fixed32(Span)

Protobut fixed32

Remarks

Always four bytes. More efficient than uint32 if values are often greater than 2^28.

Sfixed32(Span)

Protobut sfixed32

Remarks

Always four bytes.

Float(Span)

Protobut float

MessageOrEnum(Type)

Protobuf message or enum (holds the name)

Map(MapType)

Protobut map

Group(Group)

Protobuf group (deprecated)
