expected value, found struct variant EnumVariation::Rust

[lacabra]

Describe the bug
Trying to compile core on the latest develop branch errors out, but interestingly km builds just fine.

To Reproduce
Build core with:

cd enigma-core/enigma-core
make full-clean
SGX_MODE=HW RUSTFLAGS=-Awarnings RUST_BACKTRACE=1 make DEBUG=1

Expected behavior
The build should succeed.
