Struct LspTransport 

pub struct LspTransport { /* private fields */ }

LSP Transport for communicating with language servers

Implementations

impl LspTransport

pub async fn spawn( command: &str, args: &[String], timeout_ms: u64, ) -> Result<Self>

Spawn a language server and create a transport

pub async fn request( &self, method: &str, params: Option<Value>, ) -> Result<JsonRpcResponse>

Send a request and wait for response

pub async fn notify(&self, method: &str, params: Option<Value>) -> Result<()>

Send a notification (no response expected)

pub async fn diagnostics_snapshot(&self) -> HashMap<String, Vec<Diagnostic>>

Return the last diagnostics published by the language server.

pub fn diagnostics_publish_seq(&self) -> u64

Current publish sequence counter. Increments every time the language server publishes diagnostics for any URI. Callers can read this before a textDocument/didChange and then wait via Self::wait_for_publish_after for the server to republish.

pub async fn invalidate_diagnostics(&self, uri: &str)

Remove any cached diagnostics for uri. Useful before a didChange so stale entries can’t be returned while the server recomputes.

pub async fn wait_for_publish_after( &self, baseline: u64, timeout: Duration, ) -> bool

Wait until the server publishes diagnostics with a sequence greater than baseline, or the timeout elapses. Returns true if a new publication arrived in time.

pub fn is_initialized(&self) -> bool

Check if the server is initialized

pub fn set_initialized(&self, value: bool)

Mark the server as initialized
