Struct LeaseHelper

Source

pub struct LeaseHelper { /* private fields */ }

Expand description

Helper for acquiring leases. Instantiate with LeaseControl::new(), and then acquire a lease with the lease() method. The lease() call will return only once the lease is satisfied.

A single LeaseHelper may be reused to create leases an arbitrary number of times.

Implementations§

Source §

impl LeaseHelper

Source

pub async fn new<'a>( topology: &'a TopologyProxy, name: &'a str, lease_dependencies: Vec<LeaseDependency>, ) -> Result<Arc<Self>>

Creates a new LeaseHelper. Returns an error upon failure to register the to-be-leased power element with Power Broker.

Source

pub async fn create_lease_and_wait_until_satisfied( self: &Arc<Self>, ) -> Result<Lease>

Acquires a lease, completing only once the lease is satisfied. Returns an error if the underlying Lessor.Lease or LeaseControl.WatchStatus call fails.

Source

pub async fn create_lease(self: &Arc<Self>) -> Result<Lease>
