This lets you use binary notation to express numbers so you can do:

from foo
filter bar == 0b1111000011110000

Thanks for the reminder. I added it to the docs now.

Thanks! Will need a cargo insta test --accept to update the docs snapshot (also task test-rust should work)

[vanillajonathan]

Yeah, I just noticed. Fixed.
