Cfg! in lazy_static

help
#1

I have a:

if cfg!(feature = "internal") {
  // blah
}

I have it in two different different files -- in one everything works as expected, the other seems to be silently ignored. The only notable difference I can think of is that the latter one is within a lazy_static block.

Is it expected that cfg! within lazy_static! not work?

It should work fine. Perhaps post an example and explain in what manner it fails?

#3

By "the other seems to be silently ignored", do you mean that the compiler gives you compile-time errors when the feature is disabled?

If that's what's happening you can fix it by changing the code to:

#[cfg(feature = "internal")]
{
    // blah
}

It was a typo. features :expressionless:

I don't know why, but I had gotten the impression that it would error out of the feature key is not recognized. Lesson learned!
