I recently got a warning that feature
core_ffi_c is stable. However, I still have problems with
use core::ffi::c_size_t as _; // this works
use std::ffi::c_size_t as _; // this doesn't work
Is this going to be fixed eventually? (I'm often unsure whether to import things from
std, by the way. I tend to use
std everywhere but here it doesn't work.)
(Old thread on that matter when
core_ffi_c was new)
core_ffi_c is in fact on the train to stabilize in 1.64.
c_size_t is still unstable... but lacks a reëxport into std. This is a bug.
If you're using
std and not using
#![no_std], it is fine, idiomatic, and expected to import everything from
std. Every API item intended to be used by consumers is exported from
std; for a no-no-std user, the fact
std is split into crates is an implementation detail.
(In fact, there are vague plans (the "portability lint") of eventually making
std:: usable for everyone, and just feature flagging functionality between targets.)
So yes, you should just use
std::. (You know if you need to not.)
