Crate perl_lsp_transport 

LSP transport layer for perl-lsp.

This crate provides the transport layer implementation for the Perl Language Server, handling message framing according to the LSP Base Protocol specification.

Overview

The LSP Base Protocol uses Content-Length based message framing over stdio (or other transports). This crate provides:

• ContentLengthMessageReader - Stateful framed reader for streaming request loops
• read_message - Read and parse an LSP message with Content-Length framing
• write_message - Write an LSP response with proper framing
• write_notification - Write an LSP notification with proper framing
• log_response - Debug logging for outgoing responses

Example

use std::io::{BufReader, stdin, stdout};
use perl_lsp_transport::{read_message, write_message};
use perl_lsp_protocol::JsonRpcResponse;

let mut reader = BufReader::new(stdin());
let mut writer = stdout();

// Read an incoming message
if let Ok(Some(request)) = read_message(&mut reader) {
    // Process request and create response
    let response = JsonRpcResponse::null(request.id);

    // Write the response
    write_message(&mut writer, &response)?;
}
