Std in derive

[iupii]

I can't build parity-scale-codec with derive because it uses std there.
As I can see there are only

use std::str::FromStr;
use std::str::from_utf8;

Both available in core.

I have to use it with no_std, but now it's impossible.

The derive macro is allowed to use std, it is always compiled for the host. Not sure what your problem is.

I was also expecting this to be non-std (#285). Is there a way to compile parity-scale-codec with ink rc4. This was not a problem with rc3 and was possibly introduced by rc4s allocator (from reading that error message)

I repeat myself, parity-scale-derive is a proc-macro and they are always compiled for the host platform. They don't support no_std.
