A saturating add is five instructions where a wrapping one is one, and it has no i32 vector form. Measured on the fixed-shape fixture, seed 1, depth 8, 500 frames of `many`: 2,098M instructions and ~826M cycles down to 1,918M and ~771M, with `random`, `tabs` and `text` byte-identical at 1920x1200 and the 100-seed oracle passing. What saturating bought was ordering past the end of the range, where a layout is already a defect; wrapping makes that defect obvious instead of plausible. `from_f32` still clamps, since a float has the range to come from anywhere, and `narrow` stays for `Holds`, whose range past i32 really does mean unbounded. MIN and MAX remain unbounded ends only where they are compared and never added to, which is every use. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
iris
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
