Expand description

A trait marking types that define the query message(s) of a contract

This trait requires specifying a padding block size and provides a method to query a contract

Required Associated Constants§

const BLOCK_SIZE: usize

pad the message to blocks of this size

Provided Methods§

fn query<C: CustomQuery, T: DeserializeOwned>(
    &self,
    querier: QuerierWrapper<'_, C>,
    code_hash: String,
    contract_addr: String
) -> StdResult<T>

Returns StdResult, where T is the type defining the query response

Tries to query a contract and deserialize the query response. The BLOCK_SIZE specified in the implementation is used when padding the message

Arguments

querier - a reference to the Querier dependency of the querying contract
callback_code_hash - String holding the code hash of the contract to be queried
contract_addr - address of the contract being queried
