klayout-core 0.0.1

//! `klayout-core` — the foundation data model for klayout-rs.
//!
//! This crate defines coordinates, geometry primitives (data only), layers,
//! cells, ports, instances, and the parameterized-component machinery.
//! Everything else in the workspace — IO, geometry algorithms, routing,
//! DRC/LVS — sits on top of these types and is expected to honor the
//! invariants documented per-module.
//!
//! Design contract:
//! 1. Frozen cells are immutable. All mutation goes through `CellBuilder`.
//! 2. `ContentHash` is deterministic, structural, byte-stable across runs.
//! 3. All coordinates are i64 DBU. Microns are a thin conversion layer.
//! 4. `Library` is `Send + Sync`; concurrent `build`/`insert` is safe.
//! 5. `CellId` / `LayerIndex` are meaningful only with their issuing library.
//! 6. No global state. `BuildCtx` is passed.
