What I did

Updated the Rust template to show the four ritchie input methods and match the language and colors to the hello-world formula.

How I did it

Used the hello-world formula as a guideline.

How to verify it

Direct comparison to the hello-world command: rit demo hello-world.

From the fork, with the rust toolchain:

cd templates/create_formula/languages/rust/
export INPUT_TEXT=senoja
export INPUT_LIST=toils
export INPUT_BOOLEAN=false
export INPUT_PASSWORD=none

cargo run 

You might laugh but this is what I came up with for a final validation using the cli:

rit delete repo # remove commons and re-add commons from my fork
echo '{"provider":"Github", "name":"commons", "version":"exp", "url":"https://github.com/senoja/ritchie-formulas-demo", "token": null, "priority":0}' | rit add repo --stdin
rit create formula # selecting the rust option and "rit senoja rust update"
rit senoja rust update
