great video hope you can tackle complex lifetimes like multiple lifetimes in struct and methods.

9:27 Shouldn't it be the lifetime of the reference we pass into 'a in the ImportantExcerpt struct needs to live at least as long as the struct lives. They are not always the same.

We are allowed to use the first_sentence variable even after the ImportantExcerpt var gets dropped so its lifetime has to be longer.

Basically with lifetimes it's simply "I don't care how long you live if it is at least as long as I am living"

One of the most confusing things in Rust (for me)

I checked out this video hoping it might offer something new.

Content almost identical to Let's Get Rusty with same structure, examples and explanations.


(author responded to my original comment explaining that both tutorials based on the Rust Book which is correct. I'll be kind and give the benefit of the doubt, but this video is surprisingly close. Tried to edit my original comment to be less harsh, but it errored and has now disappeared. Hence this new comment.)
