Struct cosmwasm_vm::testing::MockQuerier

pub struct MockQuerier<C: CustomQuery + DeserializeOwned = Empty> { /* fields omitted */ }

MockQuerier holds an immutable table of bank balances TODO: also allow querying contracts

Implementations

impl<C: CustomQuery + DeserializeOwned> MockQuerier<C>

pub fn new(balances: &[(&str, &[Coin])]) -> Self

pub fn update_balance(
    &mut self,
    addr: impl Into<String>,
    balance: Vec<Coin>
) -> Option<Vec<Coin>>

pub fn update_staking(
    &mut self,
    denom: &str,
    validators: &[Validator],
    delegations: &[FullDelegation]
)

pub fn with_custom_handler<CH: 'static>(self, handler: CH) -> Self where
    CH: Fn(&C) -> MockQuerierCustomHandlerResult, 

impl MockQuerier

pub fn query<C: CustomQuery>(
    &self,
    request: &QueryRequest<C>,
    gas_limit: u64
) -> BackendResult<SystemResult<ContractResult<Binary>>>

Trait Implementations

impl<C: CustomQuery + DeserializeOwned> Querier for MockQuerier<C>

fn query_raw(
    &self,
    bin_request: &[u8],
    gas_limit: u64
) -> BackendResult<SystemResult<ContractResult<Binary>>>

This 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.
