```Return the serialized payload of loaded libraries.
You can restore the serialized payload later with the [`FUNCTION RESTORE`]() command.

For more information please refer to [Introduction to Redis Functions]().

## 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 LOAD "#!lua name=mylib \n redis.register_function('myfunc', function(keys, args) return args[1] end)"
"mylib"
redis> FUNCTION DUMP
"\xf5\xc3@X@]\x1f#!lua name=mylib \n redis.registe\rr_function('my@\x0b\x02', @\x06`\x12\nkeys, args) 6\x03turn`\x0c\a[1] end)\x0c\x00\xba\x98\xc2\xa2\x13\x0e$\a"
redis> FUNCTION FLUSH
OK
redis> FUNCTION RESTORE "\xf5\xc3@X@]\x1f#!lua name=mylib \n redis.registe\rr_function('my@\x0b\x02', @\x06`\x12\nkeys, args) 6\x03turn`\x0c\a[1] end)\x0c\x00\xba\x98\xc2\xa2\x13\x0e$\a"
OK
redis> FUNCTION LIST
