INHIBIT_DEFAULT_RUST_DEPS used by rust is lacking a default value and is entirely undocumented > bitbake-getvar INHIBIT_DEFAULT_RUST_DEPS returns > The variable 'INHIBIT_DEFAULT_RUST_DEPS' is not defined The code in rust bbclass is doing a "if not d.getVar('INHIBIT_DEFAULT_RUST_DEPS'):" only, so having a documented and defined empty value will not impact functionality
As per several other bugs opened of this type, we are not adding default values for the sake of it. I do agree we should document variables where possible.
