HeliosDB Full Feature Index (v8.0.3)

HeliosDB Full Feature Index (v8.0.3)

Canonical feature x source-crate x tutorial coverage map across all 193 crates. Every domain in the Full workspace is represented here with its source crate, headline UVP, and a link to a tutorial / reference / quick-start (or to CHANGELOG when no doc has shipped yet).

For overall edition positioning, see EDITION_COMPARISON_NANO_LITE_FULL. For per-version notes, see releases/.

Coverage Status Legend

  • ⭐⭐⭐⭐⭐ Tutorial + reference + UVP messaging
  • ⭐⭐⭐⭐ Tutorial OR architecture-doc + code examples
  • ⭐⭐⭐ Reference page with examples
  • ⭐⭐ Brief mention (release notes / README / Cargo.toml comment)
  • ⭐ Mentioned only in CHANGELOG / source-tree
