Struct dharitri_wasm::contract_base::BlockchainWrapper

pub struct BlockchainWrapper<A>
where
    A: BlockchainApi + StorageReadApi + ManagedTypeApi + ErrorApi,
{ /* private fields */ }

Interface to be used by the actual smart contract code.

Note: contracts and the api are not mutable. They simply pass on/retrieve data to/from the protocol. When mocking the blockchain state, we use the Rc/RefCell pattern to isolate mock state mutability from the contract interface.
