A ninth sweep, over the part no earlier round named -- the widget vocabulary and the builder methods, `Widgets`, the examples, the `util` additions and the manifests -- and once more over `77ed7a2`, the eighth sweep's own commit and so itself unreviewed. A hint overrode a rule. `declared_lens` asked `rules[axis].declared()` first and fell through to the widget's own `size_hint` whenever that answered `None` -- which it does for a share, since a share is not a declaration. So a widget carrying `width(leftover(1))` and hinting a pixel length of its own was handed a box of the hint, against the rule and against the comment inside the function: "a hint still narrows the box where no rule does". `Painter::size_hint` spells the same rule-else-hint step three hundred lines up and gets it right, with the reason written on it; both read `Widgets::exact_len` now, and `declared_lens` is the part of its answer that needs nobody to divide it. `Image` is the only widget here whose hint is a declared length, and neither the tests nor the generator builds one, so nothing in this repository could reach the difference -- which is why the dump is unchanged and why the test builds a widget of its own. It records the box it was asked in: 400 with the rule and 50 without, and 50 either way before this. Marking a widget for redraw had no name. Twenty-one sites under `tests/` said it as `widgets_mut().get_dyn_mut(id);` with the widget thrown away, five with a `let _ =` in front, one with a comment explaining what the line was for, and one wrapped in a local function called `mark`. `Widgets::mark_for_redraw` says it. `revision_cost.rs` keeps the long spelling and now says why in place: it is deliberately in the API subset an old worktree also has. `assert_same_regions` could not see the defect the eighth sweep had just fixed. It zips the warm and cold id lists, so a list naming one widget twice -- which is what `width`, `sized` and `align` giving back their own argument produces -- compares fewer boxes than it lists and says nothing about it. It now rejects a repeated id and two lists of different lengths, which also checks the nine fixtures that round left alone: all eighteen cases pass. Bare pairs where the framework has named ones. `random.rs`'s `Lens` and `Aligns` were `[Option<LayoutLen>; 2]` and `[Option<AxisAlign>; 2]`, read as `[0]`/`[1]` and zipped against a hand-written `[Axis::X, Axis::Y]`. They are `SizeRules` and `Align`; `Align` took the `Index<Axis>` every other per-axis pair on this branch has, and `RegionAlign::from` does the "an axis left out is centred" step two rigs were spelling per axis. The three sites that wrote the axis pair out say `Axis::BOTH`, which is what the rest of the layout code says. `BothAxis<T>`, `AxisT`, `XAxis` and `YAxis` -- 45 lines with a const trait, two marker types and three accessors -- have no user anywhere in the workspace. They are the mechanism `impl_axis_index!` replaced, in the file this branch took `Vec2::axis`/`axis_mut` out of. Deleted, which is a drive-by in a block the branch was already rewriting; drop it if the scope matters more. Smaller things, each in its own place: `Wrapper` arrived beside core's `WidgetWrapper`, one word for a widget that wraps a child and for a dynamic borrow guard, so the alias is gone and its two uses name `DynBorrower` -- which is what they are. `Wrapper::new`, `Wrapper::empty` and its `Default` were three names for one value, two of them unused. `Arena::get_mut` was the only `pub(crate)` among `pub` siblings on a public type. `Selector` rounded the pointer onto the pixel grid to do arithmetic on two values already there, losing the precision the platform gave it for nothing; the step between the regions is taken on the grid instead. And the two `debug` profile settings carry their reason where the next reader looks rather than only in the commit that made them, one of which was about renaming `rest`. Format, clippy with and without layout-diagnostics, and the suite (132 + 19 + 13 + 4) are clean. The cold dump over 400 depth-5 trees is byte-identical to `77ed7a2` across all 34,488 boxes, and all three seed scans pass: 400 at depth 5 in 63.27s, 1,000 at depth 6 in 160.45s, 2,000 at depth 4 in 302.52s.

My experimental attempt at a rust ui library (also my first ui library).
It's currently designed around using retained data structures (widgets), rather than diffing generated trees from data like xilem or iced. This is an experiment and I'm not sure if it's a good idea or not.
Examples are in examples, eg. cargo run --example tabs.
Goals, in general order:
- does what I want it to (text, images, video, animations)
- very easy to use ignoring ergonomic ref counting
- reasonably fast / efficient (a lot faster than electron, save battery life, try to beat iced and xilem)
dev details
not targeting web rn cause wanna use actual nice gpu features & entire point of this is to make desktop apps / not need a web browser
general ideas trynna use rn / experiment with:
- retained mode
- specifically designed around wgpu so there's no translation
- postfix functions for most things to prevent unreadable indentation (going very well)
- events can be done directly where you draw the widgets
- almost no macros in user code & actual LSP typechecking (variadic generics if you can hear me please save us)
- relative anchor + absolute offset coord system (+ "rest" / leftover during widget layout)
- single threaded ui & pass context around to make non async usage straightforward (pretty unsure about this)
- widgets store outside of the actual rendering so they can be moved around and swapped easily (unsure about this but seems to work good for now)
under heavy initial development so not gonna try to explain status, maybe check TODO for that; sizable chance it gets a rewrite once I know everything I need and what seems to work best
it's called iris because it's the structure around what you actually want to display and colorful
