Attribute Macro export 

#[export]

Customizes how a service/program method is exposed based on specified arguments.

The attribute accepts two optional arguments:

• route - Defines a custom route for the method. By default, every exposed service method is accessible via a route derived from its name, converted to PascalCase. This argument allows you to override the default route with a string of your choice.
• unwrap_result - Indicates that the method’s Result<T, E> return value should be unwrapped. If specified, the method will panic if the result is an Err.

Examples

The following example demonstrates the use of the export attribute applied to the do_something method.

• The route argument customizes the route to “Something” (convertered to PascalCase).
• The unwrap_result argument ensures that the method’s result is unwrapped, causing it to panic with the message “Something went wrong” if the result is an Err.

mod my_service {
   use sails_rs::{export, service};

   struct MyService;

   #[service]
   impl MyService {
       #[export(route = "something", unwrap_result)]
       pub fn do_something(&mut self) -> Result<u32, String> {
           Err("Something went wrong".to_string())
       }
   }
}
