type ModuleParamConfig ¶
type ModuleParamConfig struct { ParamsMsgs ModuleParamsMessages // ParamTypes is a map of parameter types to their respective MsgUpdateParam_As* // types which satisfy the oneof for the MsgUpdateParam#AsType field. Each AsType // type which the module supports should be included in this map.

ValidParams any DefaultParams any NewParamClientFn any }
ModuleParamConfig holds type information about a module's parameters update message(s) along with default and valid non-default values and a query constructor function for the module. It is used by ParamsSuite to construct and send parameter update messages and assert on their results.
type ModuleParamsMessages ¶
type ModuleParamsMessages struct { MsgUpdateParams any MsgUpdateParamsResponse any MsgUpdateParam any MsgUpdateParamResponse any QueryParamsRequest any QueryParamsResponse any }
ModuleParamsMessages holds a reference to each of the params-related message types for a given module. The values are only used for their type information which is obtained via reflection. The values are not used for their actual message contents and MAY be the zero value. If MsgUpdateParam is omitted (i.e. nil), ParamsSuite will assume that this module does not support individual parameter updates (i.e. MsgUpdateParam). In this case, MsgUpdateParamResponse SHOULD also be omitted.
type ParamType ¶
type ParamType = string
ParamType is a type alias for a module parameter type. It is the string that is returned when calling reflect.Value#Type()#Name() on a module parameter.
const ( ParamTypeInt64 ParamType = "int64" ParamTypeUint64 ParamType = "uint64" ParamTypeFloat64 ParamType = "float64" ParamTypeString ParamType = "string" ParamTypeBytes ParamType = "uint8" ParamTypeCoin ParamType = "Coin" ParamTypeMintAllocationPercentages ParamType = "MintAllocationPercentages" )
type ParamsSuite ¶

AuthorityAddr cosmostypes.AccAddress // AuthorizedAddr is the cosmos account address which is the **grantee** of authz // grants for parameter update messages. // In practice, it is the address of the foundation or the DAO. AuthorizedAddr cosmostypes.AccAddress }
ParamsSuite is an integration test suite that provides helper functions for querying module parameters and running parameter update messages. It is intended to be embedded in other integration test suites which are dependent on parameter queries or updates.
func (*ParamsSuite) QueryModuleParams ¶
