Highlight Rust Code From The Command Line With rust-analyzer

The rust-analyzer binary includes a few sub commands.
One of them is "highlight" which produces an HTML
output with highlighted code. For example, this:

-- code
-- bash

echo 'fn main() { println!("alfa"); }' \
| rust-analyzer highlight

-- p

Produces:

-- code
