Colours in (g)vim output window

Question

I've started learning Rust, and have been setting up my Vim workflow to use it. I'm still relatively new to Vim, and mostly what I've written in it is PHP for a website. Now that I'm working with a language where the code is compiled and run, I'm keen to try using the Vim command output, especially while I'm learning and just writing simple programs.

I've added a keybinding so that <C-Enter> runs the command w | !cargo run, saving my current file, then building and running the project with cargo. The command works just fine, but the output isn't quite as easy to read as using a terminal, because I lose the colours that denote errors, warnings, help, etc.

Is there a way to get these colours to show up in the (g)vim command output, to make it as nice to read as from the terminal?

For illustration, here's an example of what it looks like in my terminal:

vs. the output from gvim:

Answer 1

Should be as simple as

set go+=!

Not applicable to Neovim though. If no success switch to :terminal instead.

Answer 2

For colors

You'll probably have to use :terminal cargo run for colors; the integrated terminal supports all the usual color stuff.

The colors don't show up in !… commands because the output does not go to a TTY, and smart programs correctly disable color when they detect this case.

For Rust

As for working with rust, note that vim ships with strong support for rust (:help rust). That includes compiler/rustc.vim and compiler/cargo.vim, which can be used with :compiler + :make.

I've added a few tweaks in my setup, like my own keywordprg when RustDocFuzzy isn't available, an includeexpr I probably stole from a plugin, and the ability to select the right compiler for make based on the project layout.
