lib.rs

1//! `klayout-core` — the foundation data model for klayout-rs.
2//!
3//! This crate defines coordinates, geometry primitives (data only), layers,
4//! cells, ports, instances, and the parameterized-component machinery.
5//! Everything else in the workspace — IO, geometry algorithms, routing,
6//! DRC/LVS — sits on top of these types and is expected to honor the
7//! invariants documented per-module.
8//!
9//! Design contract:
10//! 1. Frozen cells are immutable. All mutation goes through `CellBuilder`.
11//! 2. `ContentHash` is deterministic, structural, byte-stable across runs.
12//! 3. All coordinates are i64 DBU. Microns are a thin conversion layer.
13//! 4. `Library` is `Send + Sync`; concurrent `build`/`insert` is safe.
14//! 5. `CellId` / `LayerIndex` are meaningful only with their issuing library.
15//! 6. No global state. `BuildCtx` is passed.
