### PageRequest
PageRequest is to be embedded in gRPC request messages for efficient
pagination. Ex:

 message SomeRequest {
         Foo some_parameter = 1;
         PageRequest pagination = 2;
 }


| Field | Type | Label | Description |
| ----- | ---- | ----- | ----------- |
| `key` | [bytes](#bytes) |  | key is a value returned in PageResponse.next_key to begin querying the next page most efficiently. Only one of offset or key should be set. |
| `offset` | [uint64](#uint64) |  | offset is a numeric offset that can be used when key is unavailable. It is less efficient than using key. Only one of offset or key should be set. |
| `limit` | [uint64](#uint64) |  | limit is the total number of results to be returned in the result page. If left empty it will default to a value to be set by each app. |
| `count_total` | [bool](#bool) |  | count_total is set to true to indicate that the result set should include a count of the total number of items available for pagination in UIs. count_total is only respected when offset is used. It is ignored when key is set. |
| `reverse` | [bool](#bool) |  | reverse is set to true if results are to be returned in the descending order.

<a name="cosmos.base.query.v1beta1.PageResponse"></a>

### PageResponse
PageResponse is to be embedded in gRPC response messages where the
corresponding request message has used PageRequest.

 message SomeResponse {
         repeated Bar results = 1;
         PageResponse page = 2;
 }


| Field | Type | Label | Description |
| ----- | ---- | ----- | ----------- |
| `next_key` | [bytes](#bytes) |  | next_key is the key to be passed to PageRequest.key to query the next page most efficiently |
| `total` | [uint64](#uint64) |  | total is total number of results available if PageRequest.count_total was set, its value is undefined otherwise |

## Scalar Value Types

| .proto Type | Notes | C++ | Java | Python | Go | C# | PHP | Ruby |
| ----------- | ----- | --- | ---- | ------ | -- | -- | --- | ---- |
| <a name="double" /> double |  | double | double | float | float64 | double | float | Float |
| <a name="float" /> float |  | float | float | float | float32 | 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 | int32 | int | integer | Bignum or Fixnum (as required) |
| <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 | int64 | long | integer/string | Bignum |
| <a name="uint32" /> uint32 | Uses variable-length encoding. | uint32 | int | int/long | uint32 | uint | integer | Bignum or Fixnum (as required) |
| <a name="uint64" /> uint64 | Uses variable-length encoding. | uint64 | long | int/long | uint64 | ulong | integer/string | Bignum or Fixnum (as required) |
| <a name="sint32" /> sint32 | Uses variable-length encoding. Signed int value. These more efficiently encode negative numbers than regular int32s. | int32 | int | int | int32 | int | integer | Bignum or Fixnum (as required) |
| <a name="sint64" /> sint64 | Uses variable-length encoding. Signed int value. These more efficiently encode negative numbers than regular int64s. | int64 | long | int/long | int64 | long | integer/string | Bignum |
| <a name="fixed32" /> fixed32 | Always four bytes. More efficient than uint32 if values are often greater than 2^28. | uint32 | int | int | uint32 | uint | integer | Bignum or Fixnum (as required) |
| <a name="fixed64" /> fixed64 | Always eight bytes. More efficient than uint64 if values are often greater than 2^56. | uint64 | long | int/long | uint64 | ulong | integer/string | Bignum |
| <a name="sfixed32" /> sfixed32 | Always four bytes. | int32 | int | int | int32 | int | integer | Bignum or Fixnum (as required) |
| <a name="sfixed64" /> sfixed64 | Always eight bytes. | int64 | long | int/long | int64 | long | integer/string | Bignum |
| <a name="bool" /> bool |  | bool | boolean | boolean | bool | bool | boolean | TrueClass/FalseClass |
| <a name="string" /> string | A string must always contain UTF-8 encoded or 7-bit ASCII text. | string | String | str/unicode | string | string | string | String (UTF-8) |
| <a name="bytes" /> bytes | May contain any arbitrary sequence of bytes. | string | ByteString | str | []byte | ByteString | string | String (ASCII-8BIT) |
