Trait Implementations

impl FileSystemOps for TraceFs

fn statfs( &self, _locked: &mut Locked<FileOpsCore>, _fs: &FileSystem, _current_task: &CurrentTask, ) -> Result<statfs, Errno>

Return information about this filesystem.

fn name(&self) -> &'static FsStr

fn uses_external_node_ids(&self) -> bool

Whether this file system uses external node IDs.

fn rename( &self, _locked: &mut Locked<FileOpsCore>, _fs: &FileSystem, _current_task: &CurrentTask, _old_parent: &Arc<ObjectReleaser<FsNode, FsNodeReleaserAction>>, _old_name: &BStr, _new_parent: &Arc<ObjectReleaser<FsNode, FsNodeReleaserAction>>, _new_name: &BStr, _renamed: &Arc<ObjectReleaser<FsNode, FsNodeReleaserAction>>, _replaced: Option<&Arc<ObjectReleaser<FsNode, FsNodeReleaserAction>>>, ) -> Result<(), Errno>

Rename the given node.

fn exchange( &self, _fs: &FileSystem, _current_task: &CurrentTask, _node1: &Arc<ObjectReleaser<FsNode, FsNodeReleaserAction>>, _parent1: &Arc<ObjectReleaser<FsNode, FsNodeReleaserAction>>, _name1: &BStr, _node2: &Arc<ObjectReleaser<FsNode, FsNodeReleaserAction>>, _parent2: &Arc<ObjectReleaser<FsNode, FsNodeReleaserAction>>, _name2: &BStr, ) -> Result<(), Errno>

fn unmount(&self)

Called when the filesystem is unmounted.

fn manages_timestamps(&self) -> bool

Indicates if the filesystem can manage the timestamps (i.e. ctime and mtime).

fn crypt_service(&self) -> Option<Arc<CryptService>>

Returns the crypt service associated with this filesystem, if any.
