QueryParamsRequest

QueryParamsRequest is request type for the Query/Params RPC method.

Field	Type	Label	Description
subspace	string		subspace defines the module to query the parameter for.
key	string		key defines the key of the parameter in the subspace.

QueryParamsResponse

QueryParamsResponse is response type for the Query/Params RPC method.

Field	Type	Label	Description
param	ParamChange		param defines the queried parameter.

QuerySubspacesRequest

QuerySubspacesRequest defines a request type for querying for all registered

subspaces and all keys for a subspace.

Since: cosmos-sdk 0.46

QuerySubspacesResponse

QuerySubspacesResponse defines the response types for querying for all

registered subspaces and all keys for a subspace.

Since: cosmos-sdk 0.46

Field	Type	Label	Description
subspaces	Subspace	repeated

Subspace

Subspace defines a parameter subspace name and all the keys that exist for

the subspace.

Since: cosmos-sdk 0.46

Field	Type	Label	Description
subspace	string
keys	string	repeated

Query

Query defines the gRPC querier service.

Method Name	Request Type	Response Type	Description
Params	QueryParamsRequest	QueryParamsResponse	Params queries a specific parameter of a module, given its subspace and key.

Scalar Value Types

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