Attribute Macro object

#[object]

Entry-point macro to define a Restate Virtual object.

For more details, check the service macro documentation.

Shared handlers

To define a shared handler, simply annotate the handler with the #[shared] annotation:

use restate_sdk::prelude::*;

#[restate_sdk::object]
trait Counter {
    async fn add(val: u64) -> Result<u64, TerminalError>;
    #[shared]
    async fn get() -> Result<u64, TerminalError>;
}
