pub struct LspTransport { /* private fields */ }

Transport layer for communicating with an LSP server over stdio.

Implementations

impl LspTransport

pub fn spawn(binary: &str, args: &[&str], cwd: &Path) -> Result<Self>

Spawn an LSP server process and connect to its stdio.

Errors

Returns an error if the binary cannot be spawned.

pub async fn send_request(&mut self, method: &str, params: Value) -> Result<i64>

Send a JSON-RPC request. Returns the request ID.

Errors

Returns an error on IO or serialization failure.

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

Send a JSON-RPC notification (no response expected).

Errors

Returns an error on IO or serialization failure.

pub async fn read_message(&mut self) -> Result<JsonRpcMessage>

Read the next JSON-RPC message from the server.

Errors

Returns an error on IO, framing, or JSON parse failure.

pub async fn kill(&mut self) -> Result<()>

Kill the child process.

Errors

Returns an error if the kill signal fails.

pub fn is_alive(&mut self) -> bool

Check if the child process is still running.

pub async fn write_raw(&mut self, data: &[u8]) -> Result<()>

Write raw bytes to the server’s stdin.

Errors

Returns an error on IO failure.

pub async fn flush(&mut self) -> Result<()>

Flush the writer.

Errors

Returns an error on IO failure.

pub async fn flush_writer(&mut self) -> Result<()>

Flush the write buffer. Call at the end of a batch of requests to avoid per-message syscall overhead.
