Horizontal snapping carousel centering and scaling the middle item, with customizable item width and scale factor, composable item content, selection callbacks, and selectable indicator/label.

Streaming JSON parser emitting flat token events for incremental, chunked input; supports suspending reads, building or skipping value trees, and efficient selective field extraction.

Terminal manipulation toolkit: cursor control, rich color/styling (16/256/RGB) and attributes, screen/raw-mode management, event polling (keyboard, mouse, resize), command-pattern ANSI batching.

Audio recording engine with configurable sample rate, channels, encoding and output formats, reactive state (amplitude/duration), waveform-ready visual components, optional UI and lifecycle-safe controls.

Template library demonstrating publishing to Maven Central, offering a Fibonacci sequence generator (from host-provided seeds) with accompanying tests and publishing guidance.

Ordered B-tree map and set implementing Rust std semantics, preserving upstream behavior and tests; offers stable-order iteration, efficient B-tree operations, and parity-oriented translation.

LR(1) parser generator implementing the lalrpop grammar and architecture, offering a configuration API to process .lalrpop grammars, Cargo-style conventions and code generation.

One-shot and continuous location tracking with configurable timeouts and intervals, lifecycle-aware updates, typed error returns, battery-optimized defaults, and UI-friendly factory.

3D-rendered PC game big-box UI widget with runtime or bundled textures, spine mirroring and edge-derived side colors, configurable rotation, and a reusable GL-backed loading spinner that avoids reloads.
