- Modify NativeRunningKernel and RemoteRunningKernel to return Box<dyn RunningKernel> instead of concrete types - Update Session to handle RunningKernels as trait objects - Implement trait methods for both native and remote kernels This also has remote kernel specs hooked up in a hardcoded way for now.
Pass View<Session> in to remote kernel and launch via gpui::Task

For example, it's crucial in quantum error correction and in algorithms like quantum teleportation, which is important for quantum communication.", cx);

-
-        ```rust
-        use actix_web::{web, App, HttpResponse, HttpServer, Responder};
-
-        async fn hello() -> impl Responder {
-            HttpResponse::Ok().body(\"Hello, World!\")
-        }
-
-        #[actix_web::main]
-        async fn main() -> std::io::Result<()> {
-            HttpServer::new(|| {
-                App::new()
-                    .route(\"/\", web::get().to(hello))
-            })
-            .bind(\"127.0.0.1:8080\")?
-            .run()
-            .await
-        }
-        ```
-
-        This code creates a basic web server that responds with 'Hello, World!' when you access the root URL. Here's a breakdown of what's happening:
-
-        1. We import necessary items from the `actix-web` crate.
-        2. We define an async `hello` function that returns a simple HTTP response.
-        3. In the `main` function, we set up the server to listen on `127.0.0.1:8080`.
-        4. We configure the app to respond to GET requests on the root path with our `hello` function.
-
-        To run this, you'd need to add `actix-web` to your `Cargo.toml` dependencies:
-
-        ```toml
-        [dependencies]
-        actix-web = \"4.0\"
-        ```
-
-        Then you can run the server with `cargo run` and access it at `http://localhost:8080`.".unindent(), cx);
-            thread.insert_user_message("That's great! Can you explain more about async functions in Rust?", cx);
-            thread.insert_message(Role::Assistant, "Certainly! Async functions are a key feature in Rust for writing efficient, non-blocking code, especially for I/O-bound operations. Here's an overview:
-
-        1. **Syntax**: Async functions are declared using the `async` keyword:
-
-           ```rust
-           async fn my_async_function() -> Result<(), Error> {
-               // Asynchronous code here
-           }
-           ```
-
-        2. **Futures**: Async functions return a `Future`. A `Future` represents a value that may not be available yet but will be at some point.
-
-        3. **Await**: Inside an async function, you can use the `.await` syntax to wait for other async operations to complete:
-
-           ```rust
-           async fn fetch_data() -> Result<String, Error> {
-               let response = make_http_request().await?;
-               let data = process_response(response).await?;
-               Ok(data)
-           }
-           ```
-
-        4. **Non-blocking**: Async functions allow the runtime to work on other tasks while waiting for I/O or other operations to complete, making efficient use of system resources.
-
-        5. **Runtime**: To execute async code, you need a runtime like `tokio` or `async-std`. Actix-web, which we used in the previous example, includes its own runtime.
-
-        6. **Error Handling**: Async functions work well with Rust's `?` operator for error handling.
-
-        Async programming in Rust provides a powerful way to write concurrent code that's both safe and efficient. It's particularly useful for servers, network programming, and any application that deals with many concurrent operations.".unindent(), cx);

Kyle Kelley	473bc89d3a	Allow dynamic use of RunningKernels as trait objects - Modify NativeRunningKernel and RemoteRunningKernel to return Box<dyn RunningKernel> instead of concrete types - Update Session to handle RunningKernels as trait objects - Implement trait methods for both native and remote kernels This also has remote kernel specs hooked up in a hardcoded way for now.	2024-11-20 13:18:36 -08:00

Kyle Kelley	6469500330	Implement native kernel process monitoring - Add process status monitoring for native kernels - Remove unnecessary messaging and process status tasks from Session - Refactor kernel error handling to be more centralized - Update NativeRunningKernel to handle its own process status - Simplify Session code by moving some responsibilities to NativeRunningKernel	2024-11-20 13:18:36 -08:00
Kyle Kelley	694231afd1	clean up priors	2024-11-20 13:18:36 -08:00
