Crate tokio_lsp 

tokio-lsp

A Language Server Protocol (LSP) client implementation in Rust.

This crate provides a lightweight, async-first LSP client that can be integrated into text editors and IDEs. It implements the LSP 3.16 specification and focuses on providing a clean, safe API for communicating with language servers.

Features

• Full LSP 3.16 specification support
• Async/await interface using tokio
• Type-safe message handling with serde
• Comprehensive error handling
• Transport layer abstraction

Example

use tokio_lsp::Client;
use tokio::process::{ChildStdin, ChildStdout};
use std::io::Cursor;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Example using mock streams
    let reader = Cursor::new(vec![]);
    let writer = Cursor::new(Vec::new());
    let client = Client::new(reader, writer);
    // In real usage, you'd connect to a language server process
    // and use its stdin/stdout for reader/writer
    Ok(())
}
