Struct InodeTable 

pub struct InodeTable {
    inodes: HashMap<u64, InodeEntry>,
    path_to_ino: HashMap<PathBuf, u64>,
    real_ino_map: HashMap<u64, u64>,
    query_to_ino: HashMap<String, u64>,
    next_ino: u64,
}

Inode table managing virtual and real file mappings.

Fields

inodes: HashMap<u64, InodeEntry>

Inode number -> entry

path_to_ino: HashMap<PathBuf, u64>

Path -> inode for real files

real_ino_map: HashMap<u64, u64>

Underlying inode -> our inode (for real files)

query_to_ino: HashMap<String, u64>

Query string -> inode (for query results)

next_ino: u64

Next available inode

Implementations

impl InodeTable

pub fn new() -> Self

Create a new inode table with virtual inodes initialized.

fn init_virtual_inodes(&mut self)

pub fn get(&self, ino: u64) -> Option<&InodeEntry>

Get an inode entry.

pub fn get_or_create_real(&mut self, path: PathBuf, underlying_ino: u64) -> u64

Get or create inode for a real path.

pub fn get_or_create_query_result(&mut self, parent: u64, query: String) -> u64

Get or create inode for a query result.

pub fn lookup(&mut self, ino: u64)

Increment lookup count.

pub fn forget(&mut self, ino: u64, nlookup: u64)

Decrement lookup count.

pub fn is_virtual(&self, ino: u64) -> bool

Check if inode is virtual (part of .ragfs).

pub fn get_by_path(&self, path: &PathBuf) -> Option<u64>

Get inode by path (for real files).

pub fn remove(&mut self, ino: u64)

Remove an inode entry (for deleted files). Only removes real files and query results, not virtual inodes.

pub fn update_path(&mut self, ino: u64, new_path: PathBuf)

Update the path for an existing inode (for renames).

Trait Implementations

impl Default for InodeTable

fn default() -> Self

Returns the “default value” for a type.
