Pointers In Rust || A Rough Tutorial

Жыл бұрынToday I discovered how pointers really work in Rust! So I decided I'm gonna share my example with you guys.

Apologies on the quality of the recording, I was zoomed out a bit on the terminal and I will do better next time!

It looks like this video caught the algorithm! If anyone wants to hear a very without all the "umm"s and "uhh"s then make sure to check out my less scuffed version on my other channel! kzfaq.info/get/bejne/at2SdcqT1NnZlI0.html

using raw pointers for this is a pretty bad idea, given that they're allowed to be dangling, so if a user is ever dropped or moved in memory, that pointer won't point to them anymore, and dereferencing them would be a read after free error, and casting them to a reference creates undefined behavior as the compiler assumes that references are always valid. that's why dereferencing them requires unsafe, you have to uphold the rules, not the compiler.

Looks like my video got through on the algorithm, you are absolutely right about this! This is quite frankly a very crude way of going about this but also a rather straightforward one as well. There are other ways of achieving the same thing without the "unsafe" block but still leak memory nonetheless like the Rc method using mutable borrows.

What IDE and plugins r u using? Thanks in advance

I'm not using an ide but I have configured Neovim with vim-plug. Currently the important plugins I'm using are coc, bufferline, lualine, and neo-tree. Some of those have other plugins you have to add in order for them to work but that's the basic rundown.

Why you didn't use the native built-in lsp @@DudeBroVideos

Basically, a ref is a ptr with a lifetime. This solution doesn't look useful in real cases. Maybe we need another video?
