Struct PendingClusters 

pub(super) struct PendingClusters {
    clusters_to_free: Arc<ClustersToFreeList>,
    entry: Option<ClustersToFreeEntry>,
}

Guard for newly allocated clusters that are not yet referenced by any metadata.

If the operation that allocated them fails or is cancelled (i.e. its future is dropped) before it can reference them, dropping this guard enters them into ClustersToFreeList, so they are not leaked. Once they are referenced (at least in memory), disarm the guard.

Fields

clusters_to_free: Arc<ClustersToFreeList>

List to enter the clusters into.

entry: Option<ClustersToFreeEntry>

The clusters; None when disarmed.

Implementations

impl PendingClusters

pub fn cluster(&self) -> HostCluster

First cluster of the allocation.

pub fn make_persistent(self)

Disarm the guard, moving the clusters from a pending state (to be freed when something goes wrong) to a permanent state, because they are referenced now.

Trait Implementations

impl Drop for PendingClusters

fn drop(&mut self)

Executes the destructor for this type.
