Struct cw_multi_test::App

pub struct App<Bank = BankKeeper, Api = MockApi, Storage = MockStorage, Custom = FailingModule<Empty, Empty, Empty>, Wasm = WasmKeeper<Empty, Empty>, Staking = StakeKeeper, Distr = DistributionKeeper, Ibc = FailingModule<IbcMsg, IbcQuery, Empty>, Gov = FailingModule<GovMsg, Empty, Empty>> { /* private fields */ }

Router is a persisted state. You can query this. Execution generally happens on the RouterCache, which then can be atomically committed or rolled back. We offer .execute() as a wrapper around cache, execute, commit/rollback process.

Implementations

impl App<BankKeeper, MockApi, MemoryStorage, FailingModule<ExecC, QueryC, Empty>, WasmKeeper<ExecC, QueryC>, StakeKeeper, DistributionKeeper, FailingModule<IbcMsg, IbcQuery, Empty>, FailingModule<GovMsg, Empty, Empty>>

pub fn new<F>(init_fn: F) -> Selfwhere F: FnOnce(&mut Router<BankKeeper, FailingModule<Empty, Empty, Empty>, WasmKeeper<Empty, Empty>, StakeKeeper, DistributionKeeper, FailingModule<IbcMsg, IbcQuery, Empty>, FailingModule<GovMsg, Empty, Empty>>, &dyn Api, &mut dyn Storage),

Creates new default App implementation working with Empty custom messages.

impl<BankT, ApiT, StorageT, CustomT, WasmT, StakingT, DistrT, IbcT, GovT> App<BankT, ApiT, StorageT, CustomT, WasmT, StakingT, DistrT, IbcT, GovT>where WasmT: Wasm<CustomT::ExecT, CustomT::QueryT>, BankT: Bank, ApiT: Api, StorageT: Storage, CustomT: Module, StakingT: Staking, DistrT: Distribution, IbcT: Ibc, GovT: Gov,

pub fn init_modules<F, T>(&mut self, init_fn: F) -> Twhere F: FnOnce(&mut Router<BankT, CustomT, WasmT, StakingT, DistrT, IbcT, GovT>, &dyn Api, &mut dyn Storage) -> T,

pub fn read_module<F, T>(&self, query_fn: F) -> Twhere F: FnOnce(&Router<BankT, CustomT, WasmT, StakingT, DistrT, IbcT, GovT>, &dyn Api, &dyn Storage) -> T,

impl<BankT, ApiT, StorageT, CustomT, StakingT, DistrT, IbcT, GovT> App<BankT, ApiT, StorageT, CustomT, WasmKeeper<CustomT::ExecT, CustomT::QueryT>, StakingT, DistrT, IbcT, GovT>where BankT: Bank, ApiT: Api, StorageT: Storage, CustomT: Module, StakingT: Staking, DistrT: Distribution, IbcT: Ibc, GovT: Gov, CustomT::ExecT: Clone + Debug + PartialEq + JsonSchema + DeserializeOwned + 'static, CustomT::QueryT: CustomQuery + DeserializeOwned + 'static,

pub fn store_code( &mut self, code: Box<dyn Contract<CustomT::ExecT, CustomT::QueryT>> ) -> u64

This registers contract code (like uploading wasm bytecode on a chain), so it can later be used to instantiate a contract.

pub fn contract_data(&self, address: &Addr) -> AnyResult<ContractData>

This allows to get ContractData for specific contract

pub fn dump_wasm_raw(&self, address: &Addr) -> Vec<Record>

This gets a raw state dump of all key-values held by a given contract

impl<BankT, ApiT, StorageT, CustomT, WasmT, StakingT, DistrT, IbcT, GovT> App<BankT, ApiT, StorageT, CustomT, WasmT, StakingT, DistrT, IbcT, GovT>where CustomT::ExecT: Debug + PartialEq + Clone + JsonSchema + DeserializeOwned + 'static, CustomT::QueryT: CustomQuery + DeserializeOwned + 'static, WasmT: Wasm<CustomT::ExecT, CustomT::QueryT>, BankT: Bank, ApiT: Api, StorageT: Storage, CustomT: Module, StakingT: Staking, DistrT: Distribution, IbcT: Ibc, GovT: Gov,

pub fn set_block(&mut self, block: BlockInfo)

pub fn update_block<F: Fn(&mut BlockInfo)>(&mut self, action: F)

pub fn block_info(&self) -> BlockInfo

Returns a copy of the current block_info

pub fn wrap(&self) -> QuerierWrapper<'_, CustomT::QueryT>

Simple helper so we get access to all the QuerierWrapper helpers, eg. wrap().query_wasm_smart, query_all_balances, …

pub fn execute_multi( &mut self, sender: Addr, msgs: Vec<CosmosMsg<CustomT::ExecT>> ) -> AnyResult<Vec<AppResponse>>

Runs multiple CosmosMsg in one atomic operation. This will create a cache before the execution, so no state changes are persisted if any of them return an error. But all writes are persisted on success.

pub fn wasm_sudo<T: Serialize, U: Into<Addr>>( &mut self, contract_addr: U, msg: &T ) -> AnyResult<AppResponse>

Call a smart contract in “sudo” mode. This will create a cache before the execution, so no state changes are persisted if this returns an error, but all are persisted on success.

pub fn sudo(&mut self, msg: SudoMsg) -> AnyResult<AppResponse>

Runs arbitrary SudoMsg. This will create a cache before the execution, so no state changes are persisted if this returns an error, but all are persisted on success.

Trait Implementations

impl<BankT, ApiT, StorageT, CustomT, WasmT, StakingT, DistrT, IbcT, GovT> Executor<<CustomT as Module>::ExecT> for App<BankT, ApiT, StorageT, CustomT, WasmT, StakingT, DistrT, IbcT, GovT>where CustomT::ExecT: Clone + Debug + PartialEq + JsonSchema + DeserializeOwned + 'static, CustomT::QueryT: CustomQuery + DeserializeOwned + 'static, WasmT: Wasm<CustomT::ExecT, CustomT::QueryT>, BankT: Bank, ApiT: Api, StorageT: Storage, CustomT: Module, StakingT: Staking, DistrT: Distribution, IbcT: Ibc, GovT: Gov,

fn execute( &mut self, sender: Addr, msg: CosmosMsg<CustomT::ExecT> ) -> AnyResult<AppResponse>

Runs arbitrary CosmosMsg. This will create a cache before the execution, so no state changes are persisted if this returns an error, but all are persisted on success.

fn instantiate_contract<T: Serialize, U: Into<String>>( &mut self, code_id: u64, sender: Addr, init_msg: &T, send_funds: &[Coin], label: U, admin: Option<String> ) -> AnyResult<Addr>

Create a contract and get the new address. This is just a helper around execute()

fn execute_contract<T: Serialize + Debug>( &mut self, sender: Addr, contract_addr: Addr, msg: &T, send_funds: &[Coin] ) -> AnyResult<AppResponse>

Execute a contract and process all returned messages. This is just a helper around execute(), but we parse out the data field to that what is returned by the contract (not the protobuf wrapper)

fn migrate_contract<T: Serialize>( &mut self, sender: Addr, contract_addr: Addr, msg: &T, new_code_id: u64 ) -> AnyResult<AppResponse>

Migrate a contract. Sender must be registered admin. This is just a helper around execute()

fn send_tokens( &mut self, sender: Addr, recipient: Addr, amount: &[Coin] ) -> AnyResult<AppResponse>

impl<BankT, ApiT, StorageT, CustomT, WasmT, StakingT, DistrT, IbcT, GovT> Querier for App<BankT, ApiT, StorageT, CustomT, WasmT, StakingT, DistrT, IbcT, GovT>where CustomT::ExecT: Clone + Debug + PartialEq + JsonSchema + DeserializeOwned + 'static, CustomT::QueryT: CustomQuery + DeserializeOwned + 'static, WasmT: Wasm<CustomT::ExecT, CustomT::QueryT>, BankT: Bank, ApiT: Api, StorageT: Storage, CustomT: Module, StakingT: Staking, DistrT: Distribution, IbcT: Ibc, GovT: Gov,

fn raw_query(&self, bin_request: &[u8]) -> QuerierResult

raw_query is all that must be implemented for the Querier. This allows us to pass through binary queries from one level to another without knowing the custom format, or we can decode it, with the knowledge of the allowed types. People using the querier probably want one of the simpler auto-generated helper methods
