Struct FileMetaStore 

pub struct FileMetaStore {
    pub model_name: String,
    pub dimensions: usize,
    pub last_full_index: Option<u64>,
    /* private fields */
}

Persistent store for file metadata - enables incremental indexing

Improvements over osgrep:

1. Two-level check: mtime first (fast), hash only if mtime changed
2. Tracks chunk IDs for efficient deletion on file update
3. Stores chunk count for statistics

Fields

model_name: String

Model used for indexing (invalidate if model changes)

dimensions: usize

Dimensions of embeddings

last_full_index: Option<u64>

Last full index timestamp

Implementations

impl FileMetaStore

pub fn new(model_name: String, dimensions: usize) -> Self

Create a new empty store

pub fn load_or_create( db_path: &Path, model_name: &str, dimensions: usize, ) -> Result<Self>

Load from database directory, or create new if doesn’t exist

pub fn save(&self, db_path: &Path) -> Result<()>

Save to database directory

pub fn compute_hash(path: &Path) -> Result<String>

Compute SHA256 hash of file content

pub fn check_file(&self, path: &Path) -> Result<(bool, Vec<u32>)>

Check if a file needs re-indexing Returns: (needs_reindex, existing_chunk_ids_to_delete)

pub fn update_file(&mut self, path: &Path, chunk_ids: Vec<u32>) -> Result<()>

Update metadata for a file after indexing

pub fn remove_file(&mut self, path: &Path) -> Option<FileMeta>

Mark a file as deleted

pub fn tracked_files(&self) -> impl Iterator<Item = &String>

Get all tracked files

pub fn find_deleted_files(&self) -> Vec<(String, Vec<u32>)>

Find files that were deleted (exist in store but not on disk)

pub fn stats(&self) -> FileMetaStats

Get statistics

pub fn clear(&mut self)

Clear all entries (for full re-index)

pub fn mark_full_index(&mut self)

Set last full index time
