leios-tools

Rust tooling for Ouroboros Leios, extracted from input-output-hk/ouroboros-leios with full per-directory git history preserved.

Workspaces

This repository contains three independent Cargo workspaces:

• shared-rs/ — shared crates (consensus, including the behaviour-tree engine + actuators, and tcp-model) used by the other two.
• net-rs/ — networking building blocks (net-codec, net-core, net-cli).
• sim-rs/ — the Rust Leios simulator (sim-core, sim-cli).

net-rs and sim-rs depend on shared-rs via relative ../../shared-rs/... path dependencies, so the directory layout above must be preserved.

Live-network / adversarial tooling (net-node, net-cluster, net-ui) and the behaviour-tree definitions (behaviours/) live in the separate, private leios-adversarial-tools repository. The simulator here is safe: it never connects to a real network. Behaviour-tree *.toml configs are generated on demand from that private repo and are never committed here.

Supporting files

A few files outside the workspaces are kept, with their original paths intact:

• data/simulation/config.default.yaml, config.schema.json — the default parameters and schema. sim-rs/parameters/* symlinks resolve to these via ../../data/simulation/..., so the relative layout must be kept.
• data/simulation/pseudo-mainnet/topology-v* — the pseudo-mainnet topology family used as simulator inputs.
• .github/workflows/sim-rs.yaml — CI for the sim-rs build.

Building

Each workspace builds independently from its own directory, e.g.:

cd shared-rs && cargo build
cd net-rs    && cargo build
cd sim-rs    && cargo build
