@laho So for low-level programming, or starting with it with any tool, you don't need that much information to begin with it as you don't have complex frameworks to learn. Just how you tell the toolchain where the entry point is and basic stuff like that...
Thus, it is good way to start Rust when you mind is still in virgin state and not been inducted by the cargo cult just yet ;-)

An example of “Hello World” with raw Rust:
#![feature(no_core,lang_items,start)]
#![no_core]
#![no_std]
#![no_main]
#[lang = "sized"]
pub trait Sized {}
#[lang = "copy"]
pub trait Copy {}
#[no_mangle]
#[start]
pub extern fn _start ()
{
loop {}
}
You can compile it I think with:
rustc +nightly --crate-type bin -C link-arg=-nostartfiles test.rs
In such book you could obviously use core and std but this is as minimal as it can get (almost) ;-)

Where all existing Rust books fall short is that they are not Rust books.
They are books on building software with Cargo framework.
A great "Understanding Rust" book would based only on using rustc for all examples, and in the context of that book e.g. GNU make could be used to orchestrate the builds.
Using Cargo is obviously fine but it is in the way of in-depth understanding of the language.
This also means that I really do not recommend any of the books written about Rust because they are all as useful as the Rust documentation, i.e. not that useful.
#rust #cargo

1. My calendar for 2025.
2. My security tip for 2025: use pen and paper for what it works. That info does not leak. I still plan and draft with a notebook (having a grid) and pencil.

@mtraven23 @thcrt @mallory I would have to study that further to make any conclusions but back when I read that write up in early 00's I did not know even who Joel Spolsky was I just agreed with the text :-)
If I was interpreting it on the basis that the author is also authority you would have a point but based on that it could have been written by anyone and I would still agree with the text, I think the content is still valid, right?
