I have been programming in Rust for about 8 years now. I love the language. But I feel I have some confessions I must make.

  1. I don't know if I use tabs or spaces in my final code. I just assume that it all get solved correctly by cargo fmt. I don't even understand that people have been arguing about this for real? I vaguely remember this being important in C and C++, but I am hoping I never go back to those dark days.

  2. I never do linebreaks, not even when adding my semicolons. I hit ":w" and if shit doesn't move around on my screen, I fucked up somewhere.

  3. The only lifetime I ever use is '_, 'a or 'static otherwise I give up

  4. Wtf is the 'de lifetime in serde deserialize??

  5. Rocket is the best web server

  6. I actively chose software written in Rust over other software, even if it's not better, and I argue that it is.

Okay, got that of my chest. Never dared telling anyone this before. Feels scary

  1. Wtf is the 'de lifetime in serde deserialize??

Aside from 'static (and the anonymous lifetime '_), the exact name isn't actually meaningful beyond explaining to the reader what you intend to use this lifetime for.

So, whether you call it 'a or 'de or 'database doesn't change anything about the lifetime itself.
Serde calling it the 'de lifetime is just to clarify that this is the lifetime of the deserialized object.
