Struct DiskState

Source 
struct DiskState {
    disk_image: Box<dyn AsyncDisk>,
    read_only: bool,
    sparse: bool,
    id: [u8; 20],
    worker_shared_state: Arc<RwLock<WorkerSharedState>>,
}
Expand description

Tracks the state of an anynchronous disk.

Fields§

§disk_image: Box<dyn AsyncDisk>§read_only: bool§sparse: bool§id: [u8; 20]§worker_shared_state: Arc<RwLock<WorkerSharedState>>

A DiskState is owned by each worker’s executor and cannot be shared by workers, thus worker_shared_state holds the state shared by workers in Arc.
