In Rust, what is the performance cost of using sync::Once after the initial setup?
In Rust, how does using a different primitive type (u8, i32, u64, ...) change the generated assembly?
Assembly: In all the world of the programmer, there is no more important output.
Can we make a Rust program that's as small as it's assembler equivalent?
Thanks to Address Space Layout Randomization you can use the address of a stack variable as a zero-cost random number.
Rust avoids memory copies by optimizing return value placement.
On x86 it doesn't really matter what sync::atomic::Ordering you choose.

Just a normal day reversing linked lists on the whiteboard.
It will take longer to learn than most languages, the standard library is small so you'll need dependencies, and a lot of behavior is in traits.
... because, at every new incident, your fortitude was to be called forth, and your courage exhibited; because danger and death surrounded it, and these you were to brave and overcome. For this was it a glorious, for this was it an honourable undertaking.
