4//! # rustial-engine
5//!
6//! Framework-agnostic 2.5D map engine for the [rustial](https://crates.io/crates/rustial)
7//! geospatial library.
8//!
9//! This crate owns the **core logic** of the map: camera control, layer
10//! management, tile fetching, terrain elevation, vector tessellation,
11//! 3D model placement, and the per-frame update loop that produces a
12//! [`FrameOutput`] consumed by renderers.
13//!
14//! ## Design principles
15//!
16//! | Principle | How it is enforced |
17//! |-----------|--------------------|
18//! | **No GPU code** | Zero dependency on `wgpu`, `bevy`, or any graphics API. Renderers live in separate crates. |
19//! | **No windowing** | No `winit`, no event loop. Input arrives via [`InputEvent`] values pushed by the host. |
20//! | **No async runtime** | Tile I/O uses a synchronous send/poll pattern ([`HttpClient`], [`TileSource`]) so the engine can be embedded anywhere. |
21//! | **Thread-safe** | All public types are `Send + Sync`. [`MapState`] is designed to sit behind an `RwLock`. |
22//! | **Precision** | Coordinates are `f64` (meters, WGS-84). Camera-relative rendering avoids f32 jitter at large Mercator values. |
23//!
24//! ## Module map
25//!
26//! | Module / File | Visibility | Purpose |
27//! |---------------|------------|---------|
28//! | [`camera`] | private | [`Camera`], [`CameraConstraints`], [`CameraController`], [`CameraMode`] |
29//! | [`camera_animator`] | private | [`CameraAnimator`] -- smooth zoom, rotation, and pan momentum |
30//! | [`geometry`] | private | OGC-style geometry model ([`Feature`], [`Geometry`], [`Polygon`], ...) |
31//! | [`input`] | private | [`InputEvent`] enum (Pan, Zoom, Rotate, Resize) |
32//! | [`interaction`] | **public** | Canonical interaction event and target types layered on top of picking |
33//! | [`io`] | **public** | [`HttpClient`], [`HttpRequest`], [`HttpResponse`], [`SharedHttpClient`], [`FetchPool`], [`DiskCache`]* |
34//! | [`layer`] | private | [`Layer`] trait + [`LayerId`] |
35//! | [`layers`] | **public** | [`LayerStack`], [`TileLayer`], [`VectorLayer`], [`ModelLayer`] |
36//! | [`map_state`] | private | [`MapState`], [`FrameOutput`] |
37//! | [`models`] | **public** | [`ModelMesh`], [`ModelInstance`], [`AltitudeMode`] |
38//! | [`simplify`] | private | Douglas-Peucker line simplification |
39//! | [`terrain`] | **public** | [`TerrainManager`], [`TerrainConfig`], elevation sources, mesh building |
40//! | [`tessellator`] | private | Polygon triangulation + thick-line stroking |
41//! | [`tile_cache`] | private | LRU tile cache |
42//! | [`tile_manager`] | private | Tile request scheduling with parent-tile fallback |
43//! | [`tile_request_coordinator`] | private | Cross-source tile request coordination and global budget allocation |
44//! | [`tile_source`] | private | [`TileSource`] trait, [`TileData`], [`TileDecoder`] |
45//! | [`tile_source_http`] | private | [`HttpTileSource`] (URL-template HTTP fetcher) |
46//! | [`geojson`] | **public*** | GeoJSON parser (behind the `geojson` feature flag) |
47//! | [`style`] | **public** | Map style system -- layer configuration, paint, and update logic |
48//! | [`symbols`] | **public** | Symbol and cartography foundation -- sprite atlases, placement, and collision |
49//!
50//! *Items marked with `*` require a Cargo feature flag.
51//!
52//! ## Feature flags
53//!
54//! | Flag | Default | Description |
55//! |------|---------|-------------|
56//! | `geojson` | off | Enables the GeoJSON parser ([`parse_geojson`]) and its `serde`/`serde_json` dependencies. |
57//! | `shapefile` | off | Enables the Shapefile parser ([`parse_shapefile`]) and its `shapefile` dependency. |
58//! | `gltf` | off | Enables [`ModelMesh::from_gltf`] for GLTF/GLB 3D model loading. |
59//! | `obj` | off | Enables [`ModelMesh::from_obj`] for Wavefront OBJ 3D model loading. |
60//! | `disk-cache` | off | Enables [`DiskCache`] for flat-file on-disk tile persistence. |
61//!
62//! ## Re-exported dependency
63//!
64//! This crate depends on [`glam`](https://docs.rs/glam) (workspace version)
65//! for matrix and vector math. The `glam` types appear in public signatures
66//! (e.g. [`FrameOutput::view_projection`] is a `glam::DMat4`). Downstream
67//! crates that interact with these values should use the same `glam` version
68//! declared in the workspace `Cargo.toml`.
