Function add_directory_to_tree

atomic-repository/src/tracking/tree_ops.rs:81–96

Add an empty directory to tracking explicitly. This is distinct from `add_to_tree` because it specifically handles empty directories that need to be tracked even without children. The directory will be marked with `DIR_EXPLICIT | DIR_EMPTY` flags. # Arguments `txn` - A mutable transaction `path` - The normalized directory path # Returns The allocated inode for the directory. # Example ```ru

(txn: &mut T, path: &str)

/// txn.commit()?;
/// ```
pub fn add_directory_to_tree<T: MutTxnT>(txn: &mut T, path: &str) -> TrackingResult<Inode> {
    // Allocate a new inode
    let inode = txn
        .alloc_inode()
        .map_err(|e| TrackingError::Database(e.to_string()))?;

    // Add to tree tables
    txn.put_tree(path, inode)
        .map_err(|e| TrackingError::Database(e.to_string()))?;

    // Mark as an explicit empty directory
    txn.put_directory(inode, directory_flags::explicit_empty())
        .map_err(|e| TrackingError::Database(e.to_string()))?;

    Ok(inode)
}
