- 3 screenshots at 1284x2778 (iPhone 6.5"): note list, note detail, settings - Docker WebDAV setup with 9 demo notes in Denote format for local screenshots - Fix theme not applying to NoteListView and NoteEditorView: move tint/preferredColorScheme from App.body (Scene) to RootView.body (View) so @Observable tracking works correctly - NoteEditorView (sheet) now also gets preferredColorScheme and tint directly - Add debug.password UserDefaults fallback in DEBUG builds for screenshot automation

* Why Rust?
|
|
|
|
- Memory safety without garbage collection
|
|
- Zero-cost abstractions
|
|
- Fearless concurrency
|
|
- Great tooling (cargo, clippy, rustfmt)
|
|
|
|
* Ownership Rules
|
|
|
|
1. Each value has exactly one owner
|
|
2. When the owner goes out of scope, the value is dropped
|
|
3. You can have either one mutable reference or many immutable ones
|
|
|
|
#+begin_src rust
|
|
fn main() {
|
|
let s1 = String::from("hello");
|
|
let s2 = s1; // s1 is moved, no longer valid
|
|
println!("{}", s2);
|
|
}
|
|
#+end_src

|
* The Borrow Checker
|
|
|
|
The borrow checker enforces ownership rules at compile time. This eliminates entire classes of bugs:
|
|
|
|
- Use-after-free
|
|
- Double-free
|
|
- Data races
|
|
- Null pointer dereferences
|
|
