pub(super) fn write_record(dir: &Path, record: &InstanceRecord) -> Result<()>Expand description
Write record atomically (temp file, then rename) with mode 0600 on Unix
at open time, the same care reactive::registry::write_entry_file takes
for the shared registry, which also holds keys. On Windows the file
inherits the user-only ACL of the user’s own profile directory.
