Struct App

pub struct App<Bank = BankKeeper, Api = MockApi, Storage = MockStorage, Custom = FailingModule<Empty, Empty, Empty>, Wasm = WasmKeeper<Empty, Empty>, Staking = StakeKeeper, Distr = DistributionKeeper, Ibc = IbcFailingModule, Gov = GovFailingModule> { /* 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

pub fn new<F>(remote: RemoteChannel, init_fn: F) -> AnyResult<Self>

pub fn store_wasm_code(&mut self, code: Vec<u8>) -> u64

Registers contract code (like uploading wasm bytecode on a chain), so it can later be used to instantiate a contract. Only for wasm codes

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

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

pub fn store_wasm_code_with_creator( &mut self, creator: Addr, code: Vec<u8>, ) -> u64

Registers contract code (like store_code), but takes the address of the code creator as an additional argument.

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

Registers contract code (like store_code), but takes the address of the code creator as an additional argument.

Returns a copy of the current block_info

pub fn next_address(&mut self) -> Addr

Returns a new account address

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 get_querier_storage(&self) -> AnyResult<QuerierStorage>

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<Bank: Clone, Api: Clone, Storage: Clone, Custom: Clone, Wasm: Clone, Staking: Clone, Distr: Clone, Ibc: Clone, Gov: Clone> Clone for App<Bank, Api, Storage, Custom, Wasm, Staking, Distr, Ibc, Gov>

fn clone( &self, ) -> App<Bank, Api, Storage, Custom, Wasm, Staking, Distr, Ibc, Gov>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

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 instantiate2_contract<M, L, A, S>( &mut self, code_id: u64, sender: Addr, init_msg: &M, funds: &[Coin], label: L, admin: A, salt: S, ) -> AnyResult<Addr>

where M: Serialize, L: Into<String>, A: Into<Option<String>>, S: Into<Binary>,

Instantiates a new contract and returns its predictable address. This is a helper function around execute function with WasmMsg::Instantiate2 message.

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()

impl<BankT, ApiT, StorageT, CustomT, WasmT, StakingT, DistrT, IbcT, GovT> Querier for App<BankT, ApiT, StorageT, CustomT, WasmT, StakingT, DistrT, IbcT, GovT>

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
