v1.1.0 PR #0.5 — Stdlib Utilities. Second and final PR of v1.1.0.
Seven stateless utility modules registered once at engine build:
- regex:: — is_match/find/find_all/replace/replace_all/split/captures
via the Rust regex crate (linear-time, no backtracking).
- random:: — int/float/bytes/string/uuid via OsRng (CSPRNG only;
bytes capped at 64 KiB, string at 4 KiB).
- time:: — now/now_ms/parse/format/add_seconds/diff_seconds (UTC
only, RFC 3339, checked arithmetic).
- json:: — parse/stringify/stringify_pretty (reuses the existing
dynamic <-> JSON bridge).
- base64:: — encode/decode + encode_url/decode_url, String+Blob
inputs on encode.
- hex:: — encode/decode (lowercase out, case-insensitive in).
- url:: — encode/decode + encode_query (RFC 3986 unreserved set,
BTreeMap-ordered query iteration).
Plus docs/stdlib-reference.md covering Rhai's built-in math/string/
array/map plus all seven new namespaces in one reference page, and a
CLAUDE.md pointer to that doc.
Three new workspace deps: regex 1, hex 0.4, percent-encoding 2.
+43 integration tests in crates/executor-core/tests/stdlib.rs.

PiCloud
A lightweight, self-hosted, event-driven serverless compute platform. Upload a Rhai script, get an HTTP endpoint. Designed to run on a single modest server with no idle CPU cost, and to scale out to a small cluster when you need it.
Status: Phase 1 — MVP scaffolding in progress.
The authoritative design lives in
serverless_cloud_blueprint.md.
Why
Existing serverless platforms are either cloud-locked, heavyweight, or both. PiCloud aims for the opposite end of the spectrum: one binary, one database, one reverse proxy — running on hardware you already own.
Architecture (one paragraph)
PiCloud splits into three logical services — manager (control plane: scripts, schedules, dashboard), orchestrator (per-node event ingress and dispatch), and executor (per-node Rhai sandbox) — each backed by a *-core Rust library. In MVP they run in a single process; in cluster mode they run as three binaries with one manager and one orchestrator + executor per node. Caddy fronts everything; PostgreSQL is the single source of truth.
See CLAUDE.md for working notes and serverless_cloud_blueprint.md for the full design.
Quick Start
Coming as scaffolding lands. For now:
# Rust toolchain (pinned via rust-toolchain.toml)
cargo check --workspace
# Run the all-in-one MVP binary (once main.rs is wired up)
cargo run -p picloud
