Expand description

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.

Required Methods§

👎Deprecated since 0.31.0: Only used for limited backwards compatibility tests. Never use! Use load_esdt_token_data instead.
