Struct BastionId Copy item path

An identifier used by supervisors, children groups and their elements to identify themselves, using a v4 UUID.

A BastionId is unique to its attached element and is reset when it is restarted. A special BastionId exists for the “system supervisor” (the supervisor created by the system at startup) which is a nil UUID (00000000-0000-0000-0000-000000000000).

§Example

Bastion::children(|children| {
    children.with_exec(|ctx| {
        async move {
            let child_id: &BastionId = ctx.current().id();
            // ...
        }
    })
}).expect("Couldn't create the children group.");
