pub const BANK_ID_NONE: u32 = 0xFFFF_FFFF;Expand description
The BankID value that means “no bank”.
The engine reads BankID with this as its default and then gates bank
creation by comparing the resolved value against the same literal, with
no separate check for whether the file supplied one. So an absent BankID
and one written explicitly as 0xffffffff are the same case, which is why
the view models one u32 rather than an Option that would claim to tell
them apart.
