I am not sure what the OP is using, but with LSP I do get the error message in my editor (nvim) before any compiling (though am pretty sure some checking in happening in the background).
> Compile-time Capabilities
Not sure how this makes any sense when Rust compiles to multiple targets. Should all libraries become aware of all the "capabilities" out there. Also, this already can be implemented using features and keep things minimal.
> Comptime
I can't make sense of what the OP issue is here.

The example makes no sense.
