I have started to [learn](http://rustbyexample.com/) [rust](http://rust-lang.org), and I am enjoying myself. This is a merge and update on the two fantastic blog posts on [how to setup Visual Studio Code for Rust](https://mobiarch.wordpress.com/2015/06/16/rust-using-visual-studio-code/) and [how to enable debugging](https://sherryummen.in/2016/09/02/debugging-rust-on-windows-using-visual-studio-code/). In my personal opinion, from among [all the available IDE solutions for rust](https://areweideyet.com/), this is the best.
## Setup Rust
First, [install rust](http://rustup.rs/). Open a command line window and do this:
rustup default stable-x86_64-pc-windows-gnu
cargo install racer
cargo install rustfmt
cargo install rustsym
rustup component add rust-src
rustup component add rust-docs
@ECHO OFF
FOR /F "tokens=*" %%P IN ('rustc --print sysroot') DO SET RSP=%%P
SETX RUST_SRC_PATH "%RSP%\lib\rustlib\src\rust\src"
P:\rust\test, which we set up as follows:
C:\>P:
P:\>cd rust
P:\rust>cargo new test --bin
Created binary (application) `test` project
P:\rust>cd test
P:\rust\test>dir
Volume in drive P is awesome
Volume Serial Number is DEAD-BEEF
Directory of P:\rust\test
2059-02-22 13:37 <DIR> .
2059-02-22 13:37 <DIR> ..
2059-02-22 13:37 7 .gitignore
2059-02-22 13:37 100 Cargo.toml
2059-02-22 13:37 <DIR> src
2 File(s) 107 bytes
3 Dir(s) 12 bytes free
Ctrl+Shift+X in VSC.
* Open the P:\rust\test directory in Visual Studio Code.
* If you are using git from [cygwin](https://cygwin.com), then you will get a bunch of annoying errors. [This SO answer](http://stackoverflow.com/a/37980938) gives a hint on how to solve it:
mkdir c:\cygdrive
mklink /j c:\cygdrive\c c:
mklink /j c:\cygdrive\p p:
File → Preferences → Settings and enter the following. Or, obviously, modify it according to your needs. Also see [Rusty Code's Github page](https://github.com/saviorisdead/RustyCode) for Rusty Code specific settings.
{
"editor.fontFamily": "Source Code Pro, Consolas, 'Courier New', monospace",
"editor.fontSize": 16,
"rust.formatOnSave": true
}
File → Preferences → Keyboard Shortcuts and enter the following. Again, just a recommendation.
[
{ "key": "ctrl+alt+r", "command": "workbench.action.tasks.runTask" },
{ "key": "f7", "command": "workbench.action.tasks.build" }

Command+Shift+P and select Tasks: Configure Task Runner. Enter the following. Refer to [the VSC task documentation](https://code.visualstudio.com/Docs/editor/tasks) for what is going on here.

P:\rust\test. I am not sure how much of this has to do be repeated for the next project. When the time comes, this blog post will be updated.
