I have a question about the feature flags use in the crates. I just can't understand them.
I thought the below means that we use these dependencies, when we are not in sgx environment. But is this not exactly contrary to what the intuition is? ``` [target.'cfg(not(target_env = "sgx"))'.dependencies] ``` Further, we have this: ``` #![cfg_attr(not(target_env = "sgx"), no_std)] #![cfg_attr(target_env = "sgx", feature(rustc_private))] ``` If we are not in environment sgx, we are no std. But I thought sgx is exactly the no_std environment. And I don't understand why the line below is the exact opposite. Last one: ``` #[cfg(not(target_env = "sgx"))] extern crate sgx_tstd as std; ``` which to me is also: `import extern crate sgx_tstd as std` if we are not in sgx. I have been using sgx for over a year now and never understood this. I thought it will be clear one day, but the more time passes, the more that the flags are used wrongly here. So I would finally like to know, do I lack a fundamental understanding here, or are we somewhat working against the cargo system? -- You are receiving this because you are subscribed to this thread.
