Crate henad_core

Expand description

Core traits and types for the Henad simulation engine.

authoring holds the five model traits, one per topology and backend, and the primitives their kernels call.
params, view and action hold the descriptors a model declares for its parameters, its stats and its one-off actions.
model holds SimState, the interface the runner drives.
explore plans sweeps and searches without an engine, and export writes a run’s results.
provenance identifies the build of each crate and the source of each model.

A program depends on the henad facade instead. It re-exports these items under one module tree. The authoring guide explains each trait.

Re-exports§

action: One-off steps a model offers the user, run between ticks.
authoring: The model authoring API.
explore: Building blocks for parameter sweeps over a model.
export: Writers of a run’s stat series and final state, and a writer and reader of comma-separated values (CSV) fields.
grid: The double-buffered Grid2D that holds a grid model’s cells.
helpers: Builders for parameter descriptors and stat entries, parameter value readers, and fmt_bytes.
metadata: Model metadata the engine derives from a model’s declarations.
model: The SimState interface the runner drives.
network: A dynamic graph represented using CSR-like rows of neighbours, with an edge list.
params: Parameter descriptors, the values they describe, and the ParamStore a running state keeps the values in.
provenance: Identity of compiled crates and the source of each model.
send_sync: Send and Sync bounds that relax on wasm with atomics.
spatial_hash: The counting-sort SpatialHash that agents use to find their neighbours, and the HashGrid cell geometry both backends share.
topology: Display layers a model presents, and the neighbourhood a grid rule reads.
view: Views a state passes to the renderer, and the stat values and history the UI charts.
