FxNode is a node in the filesystem hierarchy (either a file or directory).

Required Methods

fn object_id(&self) -> u64

fn parent(&self) -> Option<Arc<FxDirectory>>

fn set_parent(&self, parent: Arc<FxDirectory>)

fn open_count_add_one(&self)

fn open_count_sub_one(self: Arc<Self>)

Atomically check if this brought the count to zero while the node is marked for purge. If so, this must queue the node for tombstone the node.

fn object_descriptor(&self) -> ObjectDescriptor

Provided Methods

fn mark_to_be_purged(&self)

Marks the object to be purged. Queues the node for tombstone if open count is zero.

fn terminate(&self)

Called when the filesystem is shutting down. Implementations should break any strong reference cycles that would prevent the node from being dropped.

Trait Implementations

impl Debug for dyn FxNode

fn fmt(&self, f: &mut Formatter<'_>) -> Result
