Deep dive by implementing linked lists

  • sweeping intro to the language
  • borrow checker, immutable / shared and mutable / unique references
  • Box, Rc, Arc, RefCell
  • iterators
  • generics

Idiomatic Rust

Method chaining

Structured errors

Concurrency

https://github.com/alexpusch/rust-magic-patterns/blob/master/visual-journey-through-async-rust/Readme.md

  • Tokio async
  • Concurrency and parallelism
  • spawn blocking

https://marabos.nl/atomics/basics.html

  • Threads, thread builder, scoped
  • Dhared ownership
  • Reference counting
  • Borrowing and data races

Performance

Starting with an excellent book:

https://nnethercote.github.io/perf-book/

Optimization of slow builds

https://www.feldera.com/blog/cutting-down-rust-compile-times-from-30-to-2-minutes-with-one-thousand-crates

  • single core compilation
  • many smaller crates

Profiling

https://gendignoux.com/blog/2024/11/18/rust-rayon-optimized.html#advanced-perf-usage

Optimizations

http://pkolaczk.github.io/server-slower-than-a-laptop/

  • cargo flamegraph
  • multicore and cost of Arc
  • read-only data in cache vs frequently updated

https://willcrichton.net/notes/k-corrset/

  • Use Rust’s compiler optimizations.
  • Hash numbers instead of strings.
  • Use (indexed) vectors instead of hashmaps.
  • Use bit-sets for efficient membership tests.
  • Use SIMD for efficient bit-sets.
  • Use multi-threading to split the work over many cores.
  • Use batching to avoid a bottleneck at work distribution.

  • Parallelize with Rayon
  • Assisted by LLM

Statistical benchmarking

Rust without RAII, for fun?

https://matklad.github.io/2022/10/06/hard-mode-rust.html

  • pre-allocation instead of RAII
  • parallelism with Rayon and thread pools
  • simple memory allocator
  • bounding volume hierarchy, BVH
