Rust All the Way Down

Chapter 6 of 7 · Section 39 of 51

Sections

1. Intro

  • 1. Agenda
  • 2. Las Vegas, 2011 — where I learned to program

2. The Rails Lesson

  • 3. Convention over configuration
  • 4. The database was a shared design
  • 5. Controllers — where a request becomes a decision
  • 6. Parameter handling — the shape of what comes in
  • 7. Middleware — the layer I didn't know I needed
  • 8. "It works on my machine"
  • 9. How new all of this still was
  • 10. From Rails conventions to Navigator
  • 11. A eulogy for my programming career

3. Shared craft compounds

  • 12. Keep domain seams in Rust, where interest compounds
  • 13. Widely available — governed in the open
  • 14. A cautionary tale — Java, Oracle, and the price of a single owner
  • 15. Say it with your whole chest

4. Six ways to know a change holds

  • 16. One giant change deserves more than one glance
  • 17. The compiler asks whether the program can be true
  • 18. Clippy and rustfmt ask whether the code speaks our dialect
  • 19. Tests ask whether the promise still holds at the boundary
  • 20. Bloom turns verification into a learning loop
  • 21. Marketing copy must explain the way, not only the claim
  • 22. Three workshops, three people, one method
  • 23. Fast generation, slow enough verification

5. From Law to Workflow

  • 24. The goal — deterministic workflows from law
  • 25. Step 1 — read the law
  • 26. Step 2 — write the behavior before the code
  • 27. "It works on my machine" — so we stopped trusting my machine
  • 28. Step 3 — the template: a questionnaire and a workflow
  • 29. Step 4 — the attorney gate is a graph invariant
  • 30. Step 5 — signature is a modular step
  • 31. Step 6 — the filing, run durably
  • 32. "It works on my machine" — even when my machine dies
  • 33. Why a workflow beats a prompt
  • 34. Privacy-preserving operations are part of the product

6. Rust All the Way Down

  • 35. We did not start all Rust
  • 36. From Postgres to Rust — with a bridge
  • 37. The runtime story: keep the seam, change the engine
  • 38. One deployment bucket; many matter repositories
  • 39. Rust where we can own the path; partners at the edge
  • 40. Rust reaches the places lawyers work
  • 41. I want a commercial relationship with everything I depend on
  • 42. Always the latest, always Rust
  • 43. Swap the seam — it still works
  • 44. The crates we actually run on
  • 45. Ethics is part of the stack
  • 46. The simplest developer environment I can get away with
  • 47. The online developer environment
  • 48. "It works on my machine in the cloud — and on yours, and on my client's"
  • 49. Where we are today — live by August 19
  • 50. Betting on ourselves — Rust in peace

7. Wrap Up

  • 51. Take the method home

Rust where we can own the path; partners at the edge

The destination is not an ideological ban on vendors. Surreal Cloud, Restate Cloud, OpenObserve Cloud, Stalwart Managed Email, and Miuda PBX are the Rust-operated lanes under recorded cutover gates. Xero, DocuSign, and the SIP carrier stay at the business edge, where they provide the service we do not claim to reimplement.

Presenter notes

That is the full setup: use Rust for the integration surface we need to understand and evolve, then have a commercial relationship with the people operating the infrastructure. The mail decision is deliberately narrow: a Stalwart automation subdomain owns {project-code}@mail.<brand-domain> and no-reply@ at cutover; Google Workspace continues to hold human mail at the apex. The voice decision is equally narrow: Miuda/RustPBX owns the application side and a SIP carrier is the edge. Each production tenancy, DNS record, deliverability soak, event stream, archive proof, and vendor retirement remains a named acceptance gate — an owner decision is not evidence that a cutover happened.
