pub fn startup(
resource: ResourceFree,
options: Options<'_>,
) -> Result<(State, HeldResource), Error>Expand description
Creates the cluster, if it doesn’t already exist, and starts it in a cooperative manner.
The return value has two parts: the state, State, and the resource,
HeldResource.
The state is State::Unmodified if the cluster was already running, else
State::Modified if the cluster was created or started by this function.
The resource is Left(ResourceShared) if the cluster is already in use, or
Right(ResourceExclusive) otherwise. Typically one would drop the exclusive
hold down to shared as soon as possible, but the option is there to do
maintenance, for example, that requires an exclusive hold.
