int64

Other cases

• case double

  0 is reserved for errors. Order is weird for historical reasons.

• case float
• case uint64
• case int32

  Not ZigZag encoded. Negative numbers take 10 bytes. Use TYPE_SINT32 if negative values are likely.

• case fixed64
• case fixed32
• case bool
• case string
• case group

  Tag-delimited aggregate. Group type is deprecated and not supported after google.protobuf. However, Proto3 implementations should still be able to parse the group wire format and treat group fields as unknown fields. In Editions, the group wire format can be enabled via the message_encoding feature.

• case message

  Length-delimited aggregate.

• case bytes

  New in version 2.

• case uint32
• case `enum`
• case sfixed32
• case sfixed64
• case sint32

  Uses ZigZag encoding.

• case sint64

  Uses ZigZag encoding.
