Implementations

impl ErofsDirectory

pub fn new(volume: Arc<ErofsVolume>, node: DirectoryNode) -> Self

Trait Implementations

impl Directory for ErofsDirectory

fn open( self: Arc<Self>, scope: ExecutionScope, path: Path, flags: Flags, object_request: ObjectRequestRef<'_>, ) -> Result<(), Status>

Opens a connection to this item if the path is “.” or a connection to an item inside this one otherwise. path will not contain any “.” or “..” components.

async fn read_dirents( &self, pos: &TraversalPosition, sink: Box<dyn Sink>, ) -> Result<(TraversalPosition, Box<dyn Sealed>), Status>

Reads directory entries starting from pos by adding them to sink. Once finished, should return a sealed sink.

fn register_watcher( self: Arc<Self>, scope: ExecutionScope, mask: WatchMask, watcher: DirectoryWatcher, ) -> Result<(), Status>

Register a watcher for this directory. Implementations will probably want to use a Watcher to manage watchers.

fn unregister_watcher(self: Arc<Self>, key: usize)

Unregister a watcher from this directory. The watcher should no longer receive events.

fn open_async( self: Arc<Self>, scope: ExecutionScope, path: Path, flags: Flags, object_request: &mut ObjectRequest, ) -> impl Future<Output = Result<(), Status>> + Send

where Self: Sized,

Same as Self::open but the implementation is async. This may be more efficient if the directory needs to do async work to open the connection.

fn deprecated_open( self: Arc<Self>, _scope: ExecutionScope, flags: OpenFlags, _path: Path, server_end: ServerEnd<NodeMarker>, )

DEPRECATED - Do not implement unless required for backwards compatibility. Called when handling a fuchsia.io/Directory.DeprecatedOpen request.

impl DirectoryEntry for ErofsDirectory

fn open_entry(self: Arc<Self>, request: OpenRequest<'_>) -> Result<(), Status>

Opens this entry.

fn scope(&self) -> Option<ExecutionScope>

The scope that should own connections to this directory entry, or None if parent scope should be used (the default).

impl GetEntryInfo for ErofsDirectory

fn entry_info(&self) -> EntryInfo

This method is used to populate ReadDirents() output.

impl Node for ErofsDirectory

async fn get_attributes( &self, requested_attributes: NodeAttributesQuery, ) -> Result<NodeAttributes2, Status>

Returns node attributes (io2).

fn will_open_as_node(&self) -> Result<(), Status>

Called when the node is about to be opened as the node protocol. Implementers can use this to perform any initialization or reference counting. Errors here will result in the open failing. By default, this forwards to the infallible will_clone.

fn will_clone(&self)

Called when the node is about to be cloned (and also by the default implementation of will_open_as_node). Implementations that perform their own open count can use this. Each call to will_clone will be accompanied by an eventual call to close.

fn close(self: Arc<Self>)

Called when the node is closed.

fn link_into( self: Arc<Self>, _destination_dir: Arc<dyn MutableDirectory>, _name: Name, ) -> impl Future<Output = Result<(), Status>> + Send

where Self: Sized,

fn query_filesystem(&self) -> Result<FilesystemInfo, Status>

Returns information about the filesystem and/or volume.

fn open_as_node( self: Arc<Self>, scope: ExecutionScope, options: NodeOptions, object_request: &mut ObjectRequest, ) -> Result<(), Status>

where Self: Sized,

Opens the node using the node protocol.

fn list_extended_attributes( &self, ) -> impl Future<Output = Result<Vec<Vec<u8>>, Status>> + Send

where Self: Sized,

List extended attributes.

fn get_extended_attribute( &self, _name: Vec<u8>, ) -> impl Future<Output = Result<Vec<u8>, Status>> + Send

where Self: Sized,

Get the value for an extended attribute.

fn set_extended_attribute( &self, _name: Vec<u8>, _value: Vec<u8>, _mode: SetExtendedAttributeMode, ) -> impl Future<Output = Result<(), Status>> + Send

where Self: Sized,

Set the value for an extended attribute.

fn remove_extended_attribute( &self, _name: Vec<u8>, ) -> impl Future<Output = Result<(), Status>> + Send

where Self: Sized,

Remove the value for an extended attribute.
