Attribute Macro toy_rpc_macros::export_impl

#[export_impl]

“Export” methods in the impl block with #[export_method] attribute. Methods without the attribute will not be affected. This will also generate client stub.

When using with #[async_trait], place #[async_trait] before #[export_macro]. Under the hood, this macro generates method handlers. This macro implements the toy_rpc::util::RegisterService trait, which returns the handler hashmap when a service is registered on the server.

Note

• The default service name generated will be the same as the name of the struct.

Example - Export impl block

struct Abacus { }

#[export_impl] // This will give a default service name of "Abacus"
impl Abacus {
    #[export_method]
    async fn subtract(&self, args(i32, i32)) -> Result<i32, String> {
        // ...
    }
}
