tower-lsp VS tower

I am using nom / nom_locate to build the parser side because I've done a handful of other projects with it, and I plan to use tower-lsp to hook up the language server side.

I realize this might not be for everyone, but I'm writing it in Rust using Lib-ruby-parser and tower-lsp: two existing libraries that handle a bunch of the heavy lifting for me. I'm more productive in Rust than with Ruby at this point, despite doing Ruby full time for 15 years, plus I really really don't want to have to deal with a slow LSP--that was the whome impetus for this project. I started in the spring, made a bunch of headway, then backtracked to redo the internals to make it easier to handle monkeypatching, overriding/redefining of methods, etc. across your project.

https://github.com/ebkalderon/tower-lsp is a generalized LSP implementation in a lower-level language (Rust) so you may get a better idea by reading through that repo. It seems that the server opens a TCP socket that the client later connects to, but I'm not really sure.

I was taking a look at the tower_lsp example here (https://github.com/ebkalderon/tower-lsp/blob/master/examples/stdio.rs) and had a question about how the document sync works between the client and the server.

Mine all use [tower-lsp](https://github.com/ebkalderon/tower-lsp/) for the LSP protocol stuff, and then either [Tree-sitter](https://github.com/tree-sitter/tree-sitter) or [Nom](https://github.com/Geal/nom). If I do another I'll probably try [Chumsky](https://github.com/zesterer/chumsky) which combines some of the advantages of both.

This question is partially inspired by this PR which is kinda trying to do the same thing.

dd-trace-layer is a middleware for sending Datadog's trace. It's based on Tower and OpenTelemetry Rust.

I'm pretty sure that GCP's APIs (unlike AWS, which uses Smithy for very genuinely, very good reason) are defined using Protobuf and can be communicated with over gRPC, which means that you don't need to bind via cxx to GCP's C++ APIs. Take a look at this example using Tonic. If you're to use Tonic, you'll also be able to use Tower's middleware (main crate, http-specific) to implement retries, timeouts, tracing, and all the other things you need to be production-ready.

#[derive(Clone)] struct MyMiddleware { inner: S, } impl Service> for MyMiddleware where S: Service, Response = Response> + Clone + Send + 'static, S::Future: Send + 'static, { type Response = S::Response; type Error = S::Error; type Future = BoxFuture<'static, Result>; fn poll_ready(&mut self, cx: &mut Context<'_>) -> Poll> { self.inner.poll_ready(cx) } fn call(&mut self, mut req: Request) -> Self::Future { println!("before"); // best practice is to clone the inner service like this // see https://github.com/tower-rs/tower/issues/547 for details let clone = self.inner.clone(); let mut inner = std::mem::replace(&mut self.inner, clone); Box::pin(async move { let res: Response = inner.call(req).await?; println!("after"); Ok(res) }) } } fn main() { let app = Router::new() .route("/", get(|| async { /* ... */ })) .layer(layer_fn(|inner| MyMiddleware { inner })); }

For this tutorial, we're going to use apalis to run cron jobs in an async context. We will also look at how to decorate our jobs with tower middleware allowing us to unlock features like retries, prometheus, sentry etc

So I have now had a look at Axum and think I will give it a try. In the readme in the repository it says something about tower or tower::Service and tonic, what exactly is that? I do not understand that yet.

Better compatibility with tower ecosystem.

ratpack is idealized in the simplicity of the sinatra (ruby) framework in its goal, and attempts to be an alternative to other async HTTP frameworks such as tower, warp, axum, and tide.

i would browse the standard library, tower, nom, or my own bitvec to see layout and trait/record separation. in particular, std::io and std::net may be of use: io::Read and io::Write are pervasive examples of implementing unixy file-descriptor-like behavior in the type system

We're not there yet. I keep an eye on Tower which looks promising to build on top of. And I keep an eye on MoonZoon (full stack framework, unashamedly opinionated!).
