### Message NodeInfo
Groups the information about the NeoFS node.


| Field | Type | Label | Description |
| ----- | ---- | ----- | ----------- |
| Address | [string](#string) |  | Carries network address of the NeoFS node. |
| PublicKey | [bytes](#bytes) |  | Carries public key of the NeoFS node in a binary format. |
| Attributes | [NodeInfo.Attribute](#bootstrap.NodeInfo.Attribute) | repeated | Carries list of the NeoFS node attributes in a string key-value format. |
| state | [NodeInfo.State](#bootstrap.NodeInfo.State) |  | Carries state of the NeoFS node. |


<a name="bootstrap.NodeInfo.Attribute"></a>

### Message NodeInfo.Attribute
Groups attributes of the NeoFS node.


| Field | Type | Label | Description |
| ----- | ---- | ----- | ----------- |
| Key | [string](#string) |  | Carries string key to the node attribute. |
| Value | [string](#string) |  | Carries string value of the node attribute. |

## Scalar Value Types

| .proto Type | Notes | C++ Type | Java Type | Python Type |
| ----------- | ----- | -------- | --------- | ----------- |
| <a name="double" /> double |  | double | double | float |
| <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 |
