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§

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
