Struct FileIndexer 

pub struct FileIndexer {
    AppState: Arc<ApplicationState>,
    file_index: Arc<RwLock<FileIndex>>,
    index_directory: PathBuf,
    file_watcher: Arc<Mutex<Option<RecommendedWatcher>>>,
    indexing_semaphore: Arc<Semaphore>,
    corruption_detected: Arc<Mutex<bool>>,
}

File indexer implementation with comprehensive search capabilities

This indexer provides:

• Incremental file watching with real-time updates
• Multi-mode search (literal, regex, fuzzy)
• Symbol extraction for VSCode Outline View
• Language detection for syntax highlighting
• Index corruption detection and recovery
• Parallel indexing with resource limits

Fields

AppState: Arc<ApplicationState>

Application state

file_index: Arc<RwLock<FileIndex>>

File index with metadata and symbols

index_directory: PathBuf

Index storage directory

file_watcher: Arc<Mutex<Option<RecommendedWatcher>>>

File watcher for incremental updates

indexing_semaphore: Arc<Semaphore>

Semaphore for limiting parallel indexing operations

corruption_detected: Arc<Mutex<bool>>

Index corruption detection state

Implementations

impl FileIndexer

pub async fn new(AppState: Arc<ApplicationState>) -> Result<Self>

Create a new file indexer with comprehensive setup

Initializes the indexer with:

• Index directory creation
• Existing index loading or fresh creation
• Index corruption detection
• Service status initialization

fn ValidateAndExpandPath(path: &str) -> Result<PathBuf>

Validate and expand path with traversal protection

async fn VerifyIndexIntegrity(&self) -> Result<()>

Verify index integrity and detect corruption

pub async fn IndexDirectory( &self, path: String, patterns: Vec<String>, ) -> Result<IndexResult>

Index a directory with comprehensive validation and parallel processing

pub async fn SearchFiles( &self, query: SearchQuery, path: Option<String>, language: Option<String>, ) -> Result<PaginatedSearchResults>

Search files with multiple modes

pub async fn SearchSymbols( &self, query: &str, max_results: u32, ) -> Result<Vec<SymbolInfo>>

Search symbols across all files (for VSCode Go to Symbol)

pub async fn GetFileSymbols( &self, file_path: &PathBuf, ) -> Result<Vec<SymbolInfo>>

Get symbols for a specific file (for VSCode Outline View)

pub async fn GetFileInfo(&self, path: String) -> Result<Option<FileMetadata>>

Get file information

pub async fn GetIndexStatistics(&self) -> Result<IndexStatistics>

Get index statistics

pub async fn recover_from_corruption(&self) -> Result<()>

Recover corrupted index

Trait Implementations

impl Clone for FileIndexer

fn clone(&self) -> Self
