Simple Task-based asynchronous IO
Azul provides simple helpers for asynchronous I/O, which are thread-based. Each task is a single thread, polled for completion by azul.

Completion and highlighting
While on Linux VSCode with the Rust plugin seems to work more or less out of the box, on a Mac I needed to spend some time configuring it.
First things first though, let’s start by installing Rust version manager, rustup.
We will be using nightly version of rust as to have one version that can compile all of our tools. This is mostly due to
clippy
requiring a nightly compiler.We will need Rust Language Server to provide the code completion.
For a more wholesome experience, please have some tools as well:
Now finally, for the VSCode itself, press
cmd-p
and ext install vscode-rust
. I’m using the new Rust
extension as Rusty Code
has been discontinued.If you’re lucky - that’s it, you should have working completion and highlighting in Rust files. Check this by opening any Rust source code file.If you’re greeted by this message:
You have chosen RLS mode but neither RLS executable path is specified nor rustup is installed
- then we need to get the extension to get to know your setup a bit:In VSCode go to
Settings
using cmd-,
and put the following config elements there:As the paths in the config need to be absolute, remember to adjust to your situation (system username) accordingly.
Now when you reload and start editing a Rust file you should see
RLS: Analysis finished
on the bottom bar and the completion and highlighting should all work. Yay !Building and testing
VSCode has a system of tasks that we can leverage to run the build and test from within VSCode.If you go to
Tasks->Configure
tasks it will create an empty tasks.json
file in your repository.Change it to the following to allow for cargo
to be hooked up as your build tool and test runner.You can use
cmd-shift-b
to run the build now.Debugging
For the native debugger to work we need to install another extension to VSCode called ‘LLDB Debugger’. That would be
cmd-p
and ext install vadimcn.vscode-lldb
.Rust For Machine Learning
After reloading VSCode you should be able to set breakpoints on the side gutter and run the program using debugger by pressing
F5
. First time doing this will result in the debugger choice window. Choose LLDB Debugger
as your debugger and you will be greeted with a JSON configuration file in which you need to tell the debugger a few details on your project. It may look like this:And that should be it !
Now you should be able to set breakpoints and debug through the code.
![Learning Learning](/uploads/1/3/4/5/134552306/804970476.png)
Start the debugging session by pressing
F5
again - this should result in the build proceeding and then the debugger launching.Questions ?
