Struct LspClient 

pub struct LspClient { /* private fields */ }

LSP client over stdio transport (JSON-RPC 2.0).

Implementations

impl LspClient

pub fn start(config: &LspServerConfig, root_dir: &Path) -> Result<Self>

Start an LSP server process and perform the initialize handshake.

pub fn open_file( &mut self, rel_path: &str, content: &str, language_id: &str, ) -> Result<()>

Open a file in the language server (required before definition queries).

pub fn close_file(&mut self, rel_path: &str) -> Result<()>

Close a file in the language server.

pub fn progress_token_summary(&self) -> String

Wait for the language server to finish indexing the project.

Uses the LSP $/progress notification protocol:

1. Server sends window/workDoneProgress/create to register a progress token
2. Server sends $/progress with kind: "begin" when work starts
3. Server sends $/progress with kind: "report" for updates
4. Server sends $/progress with kind: "end" when work completes

We wait until all active progress tokens have reached “end”. Fallback: if no progress notifications arrive within initial_wait, we assume the server either doesn’t support progress or finished instantly. Get a summary of progress tokens for debugging

pub fn wait_until_ready(&mut self, max_wait: Duration) -> Result<()>

pub fn get_definition( &mut self, rel_path: &str, line: u32, character: u32, ) -> Result<Option<LspLocation>>

Get definition location for a symbol at the given position. Returns None if no definition found or definition is outside project.

pub fn get_references( &mut self, rel_path: &str, line: u32, character: u32, include_declaration: bool, ) -> Result<Vec<LspLocation>>

Find all references to the symbol at the given position. Returns locations of all call sites / usages within the project. include_declaration controls whether the definition itself is included.

pub fn get_implementations( &mut self, rel_path: &str, line: u32, character: u32, ) -> Result<Vec<LspLocation>>

Find all implementations of a trait method or interface method at the given position. Returns locations of all concrete implementations within the project.

pub fn shutdown(self) -> Result<()>

Graceful shutdown of the language server.

Trait Implementations

impl Drop for LspClient

fn drop(&mut self)

Executes the destructor for this type.
