openbim-ifc 0.8.1

//! `ifc` — the facade. Pick your codecs and domains as cargo features.
//!
//! # The shape of the library
//!
//! ```text
//!   codecs                 model                  domain views
//!   ---------------        ---------------        ------------------
//!   ifc-step      \                        /      ifc-cost
//!   ifc-xml        >----->  ifc-model  <--<       ifc-schedule
//!   (ifc-json)    /         (entities)     \      ifc-properties, ...
//! ```
//!
//! Two separations hold this together, and both are enforced by tests rather
//! than convention:
//!
//! **1. The model knows no domain semantics.** [`Model`] stores
//! `(id, type_name, attributes)` and nothing else. It has never heard of a
//! cost item. Domain crates are *views* that borrow a `&Model` and interpret
//! it, so a build without them still reads and writes their data untouched.
//!
//! **2. The model knows no serialization.** [`Codec`] is a trait *in the model
//! crate*; `ifc-step` and `ifc-xml` implement it. IFC-JSON would be a third
//! implementation, requiring no change to the model.
//!
//! # Choosing features
//!
//! | Feature | Pulls in | For |
//! | --- | --- | --- |
//! | `step` *(default)* | `ifc-step` | Reading `.ifc` files |
//! | `ifcxml` | `ifc-xml` | Reading/writing `.ifcxml` |
//! | `schema` | `ifc-schema` | Subtype queries, conformant XML names |
//! | `material-templates` | `ifc-material` + template catalog | Material PSD applicability |
//! | `cost`, `schedule`, ... | one domain crate each | Interpreting that domain |
//! | `codecs` | both codecs | |
//! | `domains` | every domain view | |
//! | `full` | everything | |
//!
//! A thin viewer takes `default-features = false, features = ["step"]` and
//! compiles no domain code and no geometry stack, while still round-tripping
//! every entity in the file.
//!
//! ```

//!
//! let model = StepCodec.read_bytes(source).unwrap();
//! assert_eq!(model.len(), 1);
//!
//! // The cost entity is present and re-exportable with no `cost` feature on.
