* on the file and use of an atomic `rename()` of the new version of the file
* over the old.
* @G_FILE_SET_CONTENTS_DURABLE: Guarantee file durability: after a crash, the
* new version of the file will be available. On Unix systems this equates to
* an `fsync()` on the file (if %G_FILE_SET_CONTENTS_CONSISTENT is unset), or
* the effects of %G_FILE_SET_CONTENTS_CONSISTENT plus an `fsync()` on the
* directory containing the file after calling `rename()`.

* guarantees if the file already exists. This may speed up file operations
* if the file doesn’t currently exist, but may result in a corrupted version
* of the new file if the system crashes while writing it.
*
* Flags to pass to g_file_set_contents_full() to affect its safety and
