Implementations

impl CpioNode

pub fn new( name: String, file_type: FileType, content: Vec<u8>, file_id: usize, ) -> Arc<Self>

Create a new CPIO node

pub fn add_child( self: &Arc<Self>, name: String, child: Arc<CpioNode>, ) -> Result<(), FileSystemError>

Add a child to this directory node

pub fn get_child(&self, name: &str) -> Option<Arc<CpioNode>>

Get a child by name

pub fn parent_file_id(&self) -> Option<u64>

pub fn from_vfsnode_arc(node: &Arc<dyn VfsNode>) -> Option<Arc<CpioNode>>

Helper to convert from Arc to Arc
