Tracking Issue for feature(core_c_str) and feature(alloc_c_string)

[joshtriplett]

Feature gate: #![feature(core_c_str)] and #![feature(alloc_c_string)]

This is a tracking issue for the availability of CStr in core and CString in alloc.

Public API

// core::ffi
pub struct CStr;
pub struct FromBytesWithNulError;

// alloc::ffi
pub struct CString;
pub struct NulError;
pub struct FromVecWithNulError;
pub struct IntoStringError;

Steps / History

• Implementation: library: Move CStr to libcore, and CString to liballoc #94079
• Final comment period (FCP)
• Stabilization PR

[joshtriplett]

core::ffi::c_* appears to be on track to stabilize in 1.63.0. Shall we do the same for core::ffi::CStr and alloc::ffi::CString?

If this ends up being done, will the type aliases in std be changed back to re-exports?
