Oris

A high-performance heap allocator, after the folk-allotters of fate.

A Rust and Zig port of Dimitar Lazarov’s HPHA (2007).

Working draft — v0.4. Design stage — stubs, coding conventions, and CI scaffolding are in place; the allocator core lands in v0.1.0.

Status

Oris is at its design-and-scaffolding stage — the design documents are settled and per-port build/CI scaffolding is in place, ahead of the v0.1.0 allocator implementation. The two foundational documents are:

• BRIEF.md — design rationale, etymological grounding, target workloads, prior-art positioning
• ROADMAP.md — milestones, versioning policy, the cross-language invariant

Structure

• Cpp/ — the canonical HPHA reference source from 2007, included for diff and reference purposes. See Cpp/NOTICE.md for the license trail.
• Rust/ — the orisnik crate (targets Rust 1.85 / edition 2024). Name reserved on crates.io at 0.0.0; allocator core forthcoming in v0.1.0.
• Zig/ — the orisnitsa module (targets Zig 0.16.0). Stub package and manifest in place; allocator core forthcoming in v0.1.0.
• .github/workflows/ — CI for both ports (3-OS matrix; Rust adds a Miri soundness lane) plus tag-driven publishing: crates.io via Trusted Publishing, and a re-rooted Zig release asset.

Coding conventions

Both ports follow the Amphigraphic Grit discipline, extended for a high-performance heap allocator (Grit-ORIS):

• Rust/CONVENTIONS.md — orisnik
• Zig/CONVENTIONS.md — orisnitsa

The two share the cross-port-invariant discipline (see ROADMAP.md): an identical public alloc/free sequence must produce identical internal state transitions across both ports. The CLAUDE.md files (repo root and one per port) wire these conventions into AI-assisted edits.
