Struct LspClient 

pub struct LspClient { /* private fields */ }

LSP Client for a single language server

Implementations

impl LspClient

pub async fn new(config: LspConfig) -> Result<Self>

Create a new LSP client with the given configuration

pub async fn for_language( language: &str, root_uri: Option<String>, ) -> Result<Self>

Create an LSP client for a specific language

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

Initialize the language server

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

Shutdown the language server

pub async fn open_document(&self, path: &Path, content: &str) -> Result<()>

Open a text document

pub async fn close_document(&self, path: &Path) -> Result<()>

Close a text document

pub async fn change_document(&self, path: &Path, content: &str) -> Result<()>

Update a text document

pub async fn go_to_definition( &self, path: &Path, line: u32, character: u32, ) -> Result<LspActionResult>

Go to definition

pub async fn find_references( &self, path: &Path, line: u32, character: u32, include_declaration: bool, ) -> Result<LspActionResult>

Find references

pub async fn hover( &self, path: &Path, line: u32, character: u32, ) -> Result<LspActionResult>

Get hover information

pub async fn document_symbols(&self, path: &Path) -> Result<LspActionResult>

Get document symbols

pub async fn workspace_symbols(&self, query: &str) -> Result<LspActionResult>

Search workspace symbols

pub async fn go_to_implementation( &self, path: &Path, line: u32, character: u32, ) -> Result<LspActionResult>

Go to implementation

pub async fn completion( &self, path: &Path, line: u32, character: u32, ) -> Result<LspActionResult>

Get code completions

pub async fn diagnostics(&self, path: &Path) -> Result<LspActionResult>

Return the most recent LSP diagnostics for a file after ensuring the document is open.

This always syncs the current on-disk content to the server via a textDocument/didChange (or didOpen the first time), then waits for a fresh publishDiagnostics from the server. Without this, edits made by file-writing tools would be invisible to the LSP’s in-memory buffer and callers would see stale pre-edit diagnostics.

pub async fn capabilities(&self) -> Option<ServerCapabilities>

Get the server capabilities

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

Check if this client handles the given file extension

pub fn handles_language(&self, language: &str) -> bool

Check if this client handles a language by name
