Struct TrackedInodeReadGuard 

pub struct TrackedInodeReadGuard<'a>(RwLockReadGuard<'a, Inode>);

A guard that provides read-only access to the in-memory Inode structure.

This guard is acquired via TrackedInode::read and ensures shared access to the inode, preventing concurrent writes.

Use Case

Use this guard when inspecting the state of an inode without making any modifications.

Example

let guard = tracked_inode.read();
println!("inode size: {}", guard.size);

Tuple Fields

0: RwLockReadGuard<'a, Inode>

Methods from Deref<Target = Inode>

pub fn into_disk_format(&self) -> Inode

Converts the in-memory Inode structure into its on-disk representation.

This is used when persisting an inode to disk, typically during checkpointing or journal submission. The returned disk_layout::Inode struct matches the format expected by the on-disk inode array.

pub fn get( &self, ffs: &FastFileSystemInner, fba: FileBlockNumber, ) -> Result<Option<LogicalBlockAddress>, KernelError>

Retrieves the logical block address (LBA) corresponding to a file block.

Arguments

• ffs: Reference to the file system.
• fba: FileBlockNumber, relative to the beginning of the file.

Returns

• Ok(lba): The logical block address where the specified file block is stored.
• Err(KernelError): If the block is not allocated or the block number is out of bounds.

Trait Implementations

impl Deref for TrackedInodeReadGuard<'_>
