### Message RequestMetaHeader
|
|
RequestMetaHeader contains information about request meta headers
|
|
(should be embedded into message)
|
|
|
|
|
|
| Field | Type | Label | Description |
|
|
| ----- | ---- | ----- | ----------- |
|
|
| TTL | [uint32](#uint32) | | TTL must be larger than zero, it decreased in every NeoFS Node |
|
|
| Epoch | [uint64](#uint64) | | Epoch for user can be empty, because node sets epoch to the actual value |
|
|
| Version | [uint32](#uint32) | | Version defines protocol version TODO: not used for now, should be implemented in future |
|
|
| Raw | [bool](#bool) | | Raw determines whether the request is raw or not |
|
|
|
|
|
|
<a name="service.ResponseMetaHeader"></a>
|
|
|
|
### Message ResponseMetaHeader
|
|
ResponseMetaHeader contains meta information based on request processing by server
|
|
(should be embedded into message)
|
|
|
|
|
|
| Field | Type | Label | Description |
|
|
| ----- | ---- | ----- | ----------- |
|
|
| Epoch | [uint64](#uint64) | | Current NeoFS epoch on server |
|
|
| Version | [uint32](#uint32) | | Version defines protocol version TODO: not used for now, should be implemented in future |

### Message RequestVerificationHeader
|
|
RequestVerificationHeader is a set of signatures of every NeoFS Node that processed request
|
|
(should be embedded into message).
|
|
|
|
|
|
| Field | Type | Label | Description |
|
|
| ----- | ---- | ----- | ----------- |
|
|
| Signatures | [RequestVerificationHeader.Signature](#service.RequestVerificationHeader.Signature) | repeated | Signatures is a set of signatures of every passed NeoFS Node |
|

|
### Message RequestVerificationHeader.Signature
|
|
|
|
|
|
|
|
| Field | Type | Label | Description |
|
|
| ----- | ---- | ----- | ----------- |
|
|
| Sign | [bytes](#bytes) | | Sign is signature of the request or session key. |
|
|
| Peer | [bytes](#bytes) | | Peer is compressed public key used for signature. |

|
|
| <a name="float" /> float | | float | float | float |
|
|
| <a name="int32" /> int32 | Uses variable-length encoding. Inefficient for encoding negative numbers – if your field is likely to have negative values, use sint32 instead. | int32 | int | int |
|
|
| <a name="int64" /> int64 | Uses variable-length encoding. Inefficient for encoding negative numbers – if your field is likely to have negative values, use sint64 instead. | int64 | long | int/long |
|
|
| <a name="uint32" /> uint32 | Uses variable-length encoding. | uint32 | int | int/long |
|
|
| <a name="uint64" /> uint64 | Uses variable-length encoding. | uint64 | long | int/long |
|
|
| <a name="sint32" /> sint32 | Uses variable-length encoding. Signed int value. These more efficiently encode negative numbers than regular int32s. | int32 | int | int |
|
|
| <a name="sint64" /> sint64 | Uses variable-length encoding. Signed int value. These more efficiently encode negative numbers than regular int64s. | int64 | long | int/long |
|
|
| <a name="fixed32" /> fixed32 | Always four bytes. More efficient than uint32 if values are often greater than 2^28. | uint32 | int | int |
|
|
| <a name="fixed64" /> fixed64 | Always eight bytes. More efficient than uint64 if values are often greater than 2^56. | uint64 | long | int/long |
|
|
| <a name="sfixed32" /> sfixed32 | Always four bytes. | int32 | int | int |
|
|
| <a name="sfixed64" /> sfixed64 | Always eight bytes. | int64 | long | int/long |
|
|
| <a name="bool" /> bool | | bool | boolean | boolean |
|
|
| <a name="string" /> string | A string must always contain UTF-8 encoded or 7-bit ASCII text. | string | String | str/unicode |
|
|
| <a name="bytes" /> bytes | May contain any arbitrary sequence of bytes. | string | ByteString | str |
