Example Analysis of linked list in Redis

This article mainly introduces the example analysis of linked list in Redis, which is very detailed and has certain reference value. Friends who are interested must finish it!

1 structure of linked list and linked list nodes

1.1 Node structure

The structure of the node looks like this:

So, connecting these nodes looks like this:

1.2 linked list structure

Of course, in addition to connecting these nodes, the linked list also has to save some other information, otherwise it is too simple, right? Then the structure of the linked list looks like this:

Head: pointer to the header of the linked list tail: pointer to the footer of the linked list len: record the length of the linked list dup: the function is used to copy the value saved by the linked list node free: the function is used to release the value saved by the linked list node match: the function is used to compare whether the value saved by the linked list node is equal to another input value

After the introduction of the structure, let's take a look at the overall picture:

Note: linked lists can hold a variety of different types of values!
