Rust pop-quiz: assets and their $USD-values

Rust pop-quiz...

... really, this quiz precedes yesterday's but, oh, well: we learn by ... well: learning.

From the marketplace-as-orderbooks-in-Rust, 

construct a table of all assets and their $USD (or ... dare I say ... $axlUSDC) values.

• (answer)

Consideration

Not all assets have an $axlUSDC order book, but all assets have a stable they're paired with, so you MAY need an $USK-to-$axlUSDC-converter thingie for ALL assets to have an $axlUSDC-basis.

I WONDER WHERE YOU COULD POSSIBLY FIND THAT?!?!?!??! 🤔

BONUS!

Construct a table of all assets and their $USK-values.

n.b.: once you address the consideration (above), this bonus is simply the dual of the $axlUSDC-table.
