+@bulk-string-reply: the serialized payload
+
+@examples
+
+The following example shows how to dump loaded libraries using `FUNCTION DUMP` and then it calls `FUNCTION FLUSH` deletes all the libraries.
+Then, it restores the original libraries from the serialized payload with `FUNCTION RESTORE`.
+
+```
+redis> FUNCTION DUMP
+"\xf6\x05mylib\x03LUA\x00\xc3@D@J\x1aredis.register_function('my@\x0b\x02', @\x06`\x12\x11keys, args) return`\x0c\a[1] end)\n\x00@\n)\x11\xc8|\x9b\xe4"
