Or what the hell do #![no_start], #![no_main], #[lang = "start"], #[start], and #[main] do?

Crate Attributes:

#![no_start]

Disable automatically linking in the native crate and thus the default start lang item.

Which means you'll probably need one of: #![no_main], #![lang = “start”] or #[start] instead
