-D_FORTIFY_SOURCE in rust shared library

help
1

I have been building shared libraries in rust for different platforms. I need the fortify security check in my shared library. gcc provides this check when compiled with the flag '-D_FORTIFY_SOURCE=2'. Does rust support this check.

['__vsnprintf_chk',
'__memcpy_chk',
'__strlen_chk',
'__read_chk',
'__vsprintf_chk',
'__strcat_chk']

These symbols are found if the flag is enabled in a C binary.

I don't believe any of those are applicable to Rust. LLVM might generate calls to memcpy, but that will be bounds checked on the Rust side, so using some _chk version wouldn't add any additional security.
