pub struct DocumentTracker { /* private fields */ }

Tracks document state across the workspace.

Implementations

impl DocumentTracker

pub fn new() -> Self

Create a new document tracker with default limits.

pub fn with_limits(limits: ResourceLimits) -> Self

Create a new document tracker with custom limits.

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

Check if a document is currently open.

pub fn get(&self, path: &Path) -> Option<&DocumentState>

Get the state of an open document.

pub fn len(&self) -> usize

Get the number of open documents.

pub fn is_empty(&self) -> bool

Check if there are no open documents.

pub fn open(&mut self, path: PathBuf, content: String) -> Result<Uri>

Open a document and track its state.

Returns the document URI for use in LSP requests.

Errors

Returns an error if:

• Document limit is exceeded
• File size limit is exceeded

pub fn update(&mut self, path: &Path, content: String) -> Option<i32>

Update a document’s content and increment its version.

Returns None if the document is not open.

pub fn close(&mut self, path: &Path) -> Option<DocumentState>

Close a document and remove it from tracking.

Returns the document state if it was open.

pub fn close_all(&mut self) -> Vec<DocumentState>

Close all documents.

pub async fn ensure_open( &mut self, path: &Path, lsp_client: &LspClient, ) -> Result<Uri>

Ensure a document is open, opening it lazily if necessary.

If the document is already open, returns its URI immediately. Otherwise, reads the file from disk, opens it in the tracker, and sends a didOpen notification to the LSP server.

Errors

Returns an error if:

• The file cannot be read from disk
• The didOpen notification fails to send
• Resource limits are exceeded
