INSIGHT

Performance With Fewer Memory Headaches

  • Rust delivers C/C++ performance while eliminating most memory and race bugs that used to consume huge debugging time.
  • Andrew Lamb experienced almost no race conditions and only one memory bug after five years using Rust professionally.
ANECDOTE

Compiler Refused Trusted C++ Patterns

  • Andrew recalls months of frustration adapting to the borrow checker after 15 years of C++ patterns.
  • The compiler refused patterns he assumed were safe until he learned Rust's ownership model.
ADVICE

Prefer Cargo Over C++ Build Complexity

  • Use Rust's built-in toolchain to avoid C++ build and dependency pain.
  • Add dependencies via Cargo instead of wrestling with legacy linkers and custom build scripts.
