Cross-language compatibility of the underlying [ProtoBuf](https://developers.google.com/protocol-buffers)-based data schema allows for usage in most other popular languages. \n\nLike most large Rust projects `layout21` is a multi-crate workspace. Some internal crates are publicly available through [crates.io](https://crates.io). The \"top-level\" [layout21](./layout21) crate includes dependencies on all, and is the easiest entry-point for using all `layout21` functionality. In `layout21`'s namespace and in documentation most child-crates are referred to by their suffixes, i.e. `layout21::raw`. \n\n| Crate       | Description | [crates.io](https://crates.io) | [docs.rs](https://docs.rs) |\n| ----------- | ----------- | ------------------------------ | -------------------------- |\n| [gds21](./gds21) | GDSII Parsing, Generation, and Manipulation | [![](https://img.shields.io/crates/v/gds21.svg)](https://crates.io/crates/gds21) | [![](https://docs.rs/gds21/badge.svg)](https://docs.rs/gds21) | \n| [lef21](./lef21) | LEF Parsing, Generation, and Manipulation   | [![](https://img.shields.io/crates/v/lef21.svg)](https://crates.io/crates/lef21) | [![](https://docs.rs/lef21/badge.svg)](https://docs.rs/lef21) | \n| [layout21protos](./layout21protos) | Protobuf Schema Definitions | | | \n| [layout21raw](./layout21raw)       | \"Raw\" geometric layout.
