FAT32 filesystem node

This structure represents a file or directory in the FAT32 filesystem. It implements the VfsNode trait to integrate with the VFS v2 architecture. Content is read/written directly from/to the block device, not stored in memory.

Fields

name: RwLock<String>

Node name

file_type: RwLock<FileType>

File type (file or directory)

metadata: RwLock<FileMetadata>

File metadata

children: RwLock<BTreeMap<String, Arc<dyn VfsNode>>>

Child nodes (for directories) - cached, but loaded from disk on demand

parent: RwLock<Option<Weak<Fat32Node>>>

Parent node (weak reference to avoid cycles)

filesystem: RwLock<Option<Weak<dyn FileSystemOperations>>>

Reference to filesystem

cluster: RwLock<u32>

Starting cluster number in FAT32

children_loaded: RwLock<bool>

Directory entries loaded flag (for directories)

Implementations

impl Fat32Node

pub fn new_file(name: String, file_id: u64, cluster: u32) -> Self

Create a new regular file node

pub fn new_directory(name: String, file_id: u64, cluster: u32) -> Self

Create a new directory node

pub fn set_parent(&self, parent: Option<Weak<Fat32Node>>)

Set the parent node (weak reference)
