axiolid 0.4.0

#![forbid(unsafe_code)]

//! Feature-gated facade for Axiolid geometry.
//!
//! Nothing is compiled unless it is asked for: `default = []`, so a consumer
//! names the capability they need and pays for that alone (kernel#9). Building
//! with no feature at all raises a `compile_error!` listing the options rather
//! than leaving an empty crate whose every call site fails as "not found".
//! `standard` reproduces the pre-0.4 default (`mesh + cpu + integration`) for
//! consumers who want the old behaviour in one line.
//!
//! Features are additive and named for geometry capabilities. No feature or
//! bundle is named after a source format, vendor or downstream product, and
//! every package behind a feature stays usable as a direct dependency.
//!
//! # Exact geometry is the primary currency
//!
//! No entry point in this facade converts exact geometry into a mesh
//! unless the caller asked for one and supplied a tolerance. Tessellation
//! is a requested OUTPUT, never a fallback:
//!
//! - `generate::GenerationRequest::ExactBRep` carries no tolerance field,
//!   so a mesh cannot be produced for it. A request it cannot satisfy
//!   exactly is refused rather than approximated.
//! - `generate::TessellationRequest` and `TessellationOptions` have no
//!   `Default`. There is no global chord error to fall back to, because
//!   acceptable error depends on source units and downstream use.
//! - A tessellated result carries the tolerance it was built to, so an
//!   approximation cannot later be mistaken for an exact value.
//!
//! `tests/exact_primary.rs` holds this to account (kernel#36).

// No capability feature is enabled, so this crate would compile to an empty
// facade and every call site would fail with a confusing "not found in this
// scope" error instead of naming the real cause (kernel#9). Fail loudly here.
//
// The guard lists ONE feature per capability family rather than every
// feature: each family entry is implied by its own bundle, so a consumer who
// enabled `brep` (which implies `surfaces` -> `curves` -> `linear`) already
// satisfies it. Listing leaves instead would make this fire spuriously.

    r#"the `axiolid` facade has no capability features enabled, so it exports nothing.

As of 0.4 `default = []`: this crate is pay-for-what-you-use and compiles only
the geometry you name. Add at least one feature in Cargo.toml.

MIGRATING FROM <=0.3 (default was `mesh + cpu + integration`):
    axiolid = { version = "0.4", features = ["standard"] }

PICK BY TASK -- narrowest feature that does the job:
    triangle meshes, no operations .. "mesh"
    line/plane/ray intersection ..... "linear-intersection"
    volume, area, centroid .......... "measure"
    ray casting against a mesh ...... "ray-mesh"
    boolean union/difference ........ "application"
    planar section / contours ....... "application"
    NURBS curves and surfaces ....... "nurbs"
    exact B-rep topology ............ "brep"
    tessellate exact -> mesh ........ "tessellation"
    point clouds to mesh ............ "pointcloud-provider"
    2D fields, morphology ........... "field-ops"
    mesh repair / healing ........... "heal"

BUNDLES -- use when you want breadth over a minimal build:
    "standard" ... the pre-0.4 default: mesh + cpu + integration
    "discrete" ... mesh stack: booleans, sections, measure, spatial, generate
    "parametric" . exact stack: curves, surfaces, topology, NURBS
    "advanced" ... discrete + parametric + heal
    "full" ....... everything, including parallel/simd/gpu adapters

IMPORTANT -- features are ADDITIVE and imply their prerequisites, so name the
capability you need, not its dependencies. "brep" already pulls surfaces,
curves and linear; adding them by hand only widens your build.

Operations that dispatch to a provider (booleans, sections) need BOTH a
contract and a registered provider. "application" is the supported
combination; "mesh-boolean" alone gives you the trait with nothing behind it.
