cast-spec vs rpm-spec-profile vs cast-os-stdlib
Side-by-side comparison of Rust crates
43
cast-spec
experimentalv0.1.0
Experimental: Compile-time architectural annotations for Rust — function-shaped macros that name concepts, rules, anti-patterns, and pipelines, plus an opt-in static analyzer that validates them with rust-analyzer.
46
rpm-spec-profile
experimentalv0.1.1
Distribution profiles for the RPM spec analyzer: identity, macros, rpmlib features, whitelists
43
cast-os-stdlib
experimentalv0.1.0
Experimental: A curated library of reusable OS-level architectural concepts expressed in cast vocabulary. Downstream OS/kernel/cluster projects pull this in and reference its concepts via cast::continues_in! rather than re-deriving the same patterns inline.
