pub fn shutdown(
    resource: ResourceShared<'_>
) -> Result<(State, Either<ResourceShared<'_>, ResourceExclusive<'_>>), Error>

Expand description

Shuts down the cluster if it is running and if there are no other concurrent users.

The return value has two parts: the state, State, and the resource.

The state is State::Unmodified if the cluster could not be shut down or if it was already shut down, else State::Modified.

The resource is [Left(ResourceShared)] if the cluster is already in use – i.e. the resource passed in is returned – else [Right(ResourceExclusive)] otherwise.
