Expand description

This trait indicates a directory that can be mutated by adding and removing entries. This trait must be implemented to use a MutableConnection, however, a directory could also implement the DirectlyMutable type, which provides a blanket implementation of this trait.

Required Methods§

Source

fn update_attributes( &self, attributes: MutableNodeAttributes, ) -> impl Future<Output = Result<(), Status>> + Send
where Self: Sized,

Set the mutable attributes of this directory based on the values in attributes. If the directory does not support updating all of the specified attributes, implementations should fail with ZX_ERR_NOT_SUPPORTED.

Removes an entry from this directory.

Source

fn sync(&self) -> impl Future<Output = Result<(), Status>> + Send
where Self: Sized,

Syncs the directory.

Provided Methods§

Adds a child entry to this directory. If the target exists, it should fail with ZX_ERR_ALREADY_EXISTS.

Source

fn rename( self: Arc<Self>, _src_dir: Arc<dyn MutableDirectory>, _src_name: Path, _dst_name: Path, ) -> BoxFuture<'static, Result<(), Status>>

Renames into this directory.

Creates a symbolic link.

Source

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

List extended attributes.

Source

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.

Source

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.

Source

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

Remove the value for an extended attribute.
