Does test-rust flag requires test flag? Seems like so.
test-rust is a hack to allow us to control Rust test dependencies so we can mask it on various arches. Enabling it/disabling it does not control whether tests are run. so no, it doesn't require the test use flag, unless you mean "to run tests", in which case you need FEATURES=test anyway.
Should it be turned off by default, shouldn't it?
(In reply to Alexander Kurakin from comment #2) > Should it be turned off by default, shouldn't it? No, it's forced-on for arches which have Rust support. It does nothing unless tests are enabled (and USE=test). If it were turned off by default, it would make running tests harder, as "FEATURES=test" would have to magically turn on USE=test-rust too. There is no downside to it being forced on.
Thanks!
