const NSTDCStr *cstr - The unowned C string slice.

Returns

NSTDOptionalCString cstring - The new owned version of cstr on success, or an uninitialized “none” variant if allocating fails.

The caller of this function must ensure the following preconditions:

cstr’s data is valid for reads.
cstr does not contain any null ('\0') bytes.
