Golang Data Structures For Beginners - Generic SafeMap

Показать описание

In this Golang tutorial, I will teach you how to make a generic concurrent safe map data structure. The standard map in Golang is not safe for concurrent use. We will use Golang generics to implement our own concurrent safe hash map. If you are willing to learn more about the go programming language consider subscribing to my channel!

Very useful video, thank you
Incidentally
Defer is very important in some cases. for example:

conn.fetch ()
conn.close ()

VS

defer conn.close ()
conn.fetch ()

When the fetch() fails, a resource leak occurs. But with defer r, we are sure that the conn was closed and the memory was released

Hi Anthony. Thank you for your outstanding work. Also great to see your subs are increasing at a rapid pace.

Hello, thank you for this video. Can i ask one thing ? What if i want to have structure with more fields and i need lock just some of these fields at the same time and second part of the struct will be locked in different useCase. What is clean way to have two mutexes in one struct? I tried it and it looks like mess to me plus i am not sure which mutex it applied for which field... Thanks, Karel.

8:30 I am pretty sure since 1.14 'defer' has been fixed and doesn't incur any overhead.

fieldtrip

next step would be implementing lockless map :)
