Quasi-quoting toolkit enabling code-as-data generation of token streams via quote-like macro syntax: interpolation, repetition, identifier construction, span-aware hygiene, and composable token fragments for code generation.

Wrapper around compiler's procedural-macro API, enabling proc-macro-like token streams outside macros, making macro logic unit-testable; faithful line-by-line transliteration preserving upstream behavior and provenance.

Modular client SDK: unified networking, encrypted settings, security policies and MFA, multi-method identity and session management, WebSocket lifecycles, pluggable error parsers, composable UI and navigation.

Composable tree view with lazy rendering, connector lines drawn in one layout pass to avoid flicker, configurable indentation, icons, gaps, and optional always-expanded mode.

Client for YAXI Open Banking services handling interactive consent flows, dialogs and redirects; returns JWT-authenticated results, session/connection reuse, async CompletableFuture facade and refresh support.

Physics-based cycling simulator converting static GPX traces into virtual rides with realistic speeds, times and power estimates; elevation correction via Terrarium DEM, smoothing, resampling and GPX output.

Ergonomic trait-object error type for idiomatic application error handling; attach contextual messages, downcast to concrete error types, capture backtraces, and create errors with concise macros.
