/// The smart contract macros will automatically also generate trait implementations for this type. These include:
/// - the contract trait
/// - the `AutoImpl` trait
/// - the `EndpointWrappers` trait
///
/// When generating WASM, this contract implementation is used.
/// This makes sure no monomorphization-induced code duplication occurs in relation to modules.
