Abstraction over interior mutable types
A GAT-based library for writing code that is generic over exterior/interior mutability and mutability of references.
Pure-Rust AV1 codec — orphan-rebuild scaffold pending clean-room re-implementation.
A highly parallel Perl 5 interpreter written in Rust
HTML5 parser: tokenizer + tree builder producing a Document tree of Element/Text/Comment nodes. No mut, no Rc/Arc, no interior mutability, no panics, exhaustive matches. First sub-crate of a Servo-replacement webview runtime targeting Tauri.
ECMAScript runtime: native built-ins (console, Math, JSON, parseInt, isNaN, ...) that the boa-cat engine exposes to scripts. Each built-in is a NativeFn registered into the initial environment. No mut, no Rc/Arc, no interior mutability, no panics.
Display-list construction: walks a layout-cat LayoutTree and emits a sequence of PaintCommands (FillRect, StrokeRect, FillText) for a backend renderer to consume. Backend-agnostic; no platform graphics dependencies. No mut, no Rc/Arc, no interior mutability, no panics, exhaustive matches. Fifth sub-crate of a Servo-replacement webview runtime targeting Tauri.
Persistent DOM model: arena-backed Node tree with mutation API and CSS-selector matching. Consumes html-cat trees; selectors via css-cat. No mut, no Rc/Arc, no interior mutability, no panics, exhaustive matches. Third sub-crate of a Servo-replacement webview runtime targeting Tauri.
Tree-walking ECMAScript interpreter built on ecma-syntax-cat. Evaluates Script programs to Values with a persistent heap and lexical environment, plus native (Rust-implemented) callables for embedder-supplied built-ins. No mut, no Rc/Arc, no interior mutability, no panics, exhaustive matches. Comp-cat-rs reformulation of the Boa engine core, targeting Tauri integration.
Box-model layout: cascade + block layout over a dom-cat tree using css-cat stylesheets. Produces a LayoutBox tree with positions and dimensions. No mut, no Rc/Arc, no interior mutability, no panics, exhaustive matches. Fourth sub-crate of a Servo-replacement webview runtime targeting Tauri.
Bindings between boa-cat (JS engine) and the DOM (html-cat tree) plus fetch (net-cat). Exposes `document`, `Element` methods, and `fetch` as boa-cat NativeFns so scripts can read/mutate a parsed HTML document and make synchronous HTTP requests. v0.2.0 adds `extract_document` that walks the post-script JS-side DOM tree and reconstructs a `dom_cat::Document` so callers can back-propagate scripted mutations into layout-cat. No mut, no Rc/Arc, no interior mutability, no panics. Seventh sub-crate of a Servo-replacement webview runtime targeting Tauri.
