Dark theme and monospace font in VS Code for Rust?

Greetings

I have a survey-style question.
Dark Theme and Font?

I use VS Code (latest version) with dark theme in Rust.

I wonder what is the most popular or best or most suitable for Rust VS Code Dark theme?
And also which monospace source code font is optimal fit for Rust?

I use Dark+ night/dark VS Code theme with "Source Code Pro" monospace font.

What are you folks using that you can highly recommend?
I realize it is a matter of taste/style but perhaps there is a bit more optical science in it?

Thank you!

Personally I use Release Fantasque Sans Mono 1.7.2 · belluzj/fantasque-sans · GitHub, but v1.8 has coding ligatures if you like those.

thanks!
what dark theme do you use/recommend?
