Attribute Macro component 

#[component]

Generates the WIT interface and storage metadata.

NOTE: Mark each type used in the public method with #[export_type] attribute macro.

To disable WIT interface generation:

• don’t use #[component] attribute macro in the impl MyAccountType section;

To use manually crafted WIT interface:

• put WIT interface file in the wit folder;
• call miden::generate!(); and bindings::export!(MyAccountType);
• implement impl Guest for MyAccountType;
