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.

Provided Methods§

fn call_value(&self) -> CallValueWrapper<Self::Api>

Gateway into the call value retrieval functionality. The payment annotations should normally be the ones to handle this, but the developer is also given direct access to the API.
