Struct FileTracker 

pub struct FileTracker { /* private fields */ }

Tracks which files are open in the LSP server.

LSP requires textDocument/didOpen before any queries on a file. This tracker ensures idempotent opens and bulk close on shutdown.

Implementations

impl FileTracker

pub fn new(language: Language) -> Self

Create a new tracker for the given language.

pub async fn ensure_open( &mut self, path: &Path, transport: &mut LspTransport, ) -> Result<()>

Ensure a file is open in the LSP server. If already open, this is a no-op.

Errors

Returns an error if the file can’t be read or the notification fails.

pub async fn open_with_content( &mut self, path: &Path, uri: &str, content: &str, transport: &mut LspTransport, ) -> Result<()>

Open a file with pre-read content (avoids duplicate disk I/O during indexing).

Errors

Returns an error if the notification fails.

pub async fn reopen( &mut self, path: &Path, transport: &mut LspTransport, ) -> Result<()>

Force-reopen a file, sending fresh content to the LSP.

Unlike ensure_open, this always sends didClose (if already open) followed by didOpen with the current on-disk content. Use this after a file has been edited so the language server analyses the new version.

Errors

Returns an error if the file can’t be read or the notification fails.

pub async fn close( &mut self, path: &Path, transport: &mut LspTransport, ) -> Result<()>

Close a file in the LSP server.

Errors

Returns an error if the notification fails.

pub async fn close_all(&mut self, transport: &mut LspTransport) -> Result<()>

Close all open files.

Errors

Returns an error if any close notification fails.

pub fn is_open(&self, path: &Path) -> bool

Check if a file is currently open.

pub fn open_count(&self) -> usize

Number of currently open files.
