Struct cw_multi_test::BankKeeper

pub struct BankKeeper {}

A structure representing a default bank keeper.

Manages financial interactions in CosmWasm tests, such as simulating token transactions and account balances. This is particularly important for contracts that deal with financial operations in the Cosmos ecosystem.

Implementations

impl BankKeeper

pub fn new() -> Self

Creates a new instance of a bank keeper with default settings.

pub fn init_balance( &self, storage: &mut dyn Storage, account: &Addr, amount: Vec<Coin> ) -> AnyResult<()>

Administration function for adjusting bank accounts in genesis.

pub fn set_denom_metadata( &self, bank_storage: &mut dyn Storage, denom: String, metadata: DenomMetadata ) -> AnyResult<()>

Administration function for adjusting denomination metadata.

Trait Implementations

impl Default for BankKeeper

fn default() -> BankKeeper

Returns the “default value” for a type.

impl Module for BankKeeper

type ExecT = BankMsg

Type of messages processed by the module instance.

type QueryT = BankQuery

Type of queries processed by the module instance.

type SudoT = BankSudo

Type of privileged messages used by the module instance.

fn execute<ExecC, QueryC>( &self, _api: &dyn Api, storage: &mut dyn Storage, _router: &dyn CosmosRouter<ExecC = ExecC, QueryC = QueryC>, _block: &BlockInfo, sender: Addr, msg: BankMsg ) -> AnyResult<AppResponse>

Runs any ExecT message, which can be called by any external actor or smart contract.

fn query( &self, api: &dyn Api, storage: &dyn Storage, _querier: &dyn Querier, _block: &BlockInfo, request: BankQuery ) -> AnyResult<Binary>

Runs any QueryT message, which can be called by any external actor or smart contract.

fn sudo<ExecC, QueryC>( &self, api: &dyn Api, storage: &mut dyn Storage, _router: &dyn CosmosRouter<ExecC = ExecC, QueryC = QueryC>, _block: &BlockInfo, msg: BankSudo ) -> AnyResult<AppResponse>

Runs privileged actions, like minting tokens, or governance proposals. This allows modules to have full access to these privileged actions, that cannot be triggered by smart contracts.
