How to Use These References

📖 For learning

Read top to bottom. Each reference is written to build understanding, not just list syntax. Follow the examples in a real project.

🔍 For daily lookup

Use the sticky navigation bar at the top of each file to jump directly to the section you need — ownership, lifetimes, traits, etc.

🖨 For printing

Every file has print styles built in. Open the file, hit Cmd/Ctrl+P. The nav bar hides automatically and font sizes adjust.

💾 Fully offline

No CDN, no internet required. Keep the entire folder on your machine, USB drive, or shared on a local network.

"The references you reach for most are the ones you built yourself. These exist so you stop googling the same things twice."
