func AtomicWriteFile ¶

func AtomicWriteFile(
	path string,
	perm os.FileMode,
	write func(io.Writer) error,
) error

AtomicWriteFile safely replaces a file using a temporary file and an atomic rename.

The temporary file is created in the destination directory to ensure the rename operation is atomic on the same filesystem.

On success, the destination file is either completely replaced or left untouched if an error occurs.
