#![cfg_attr(test, allow(clippy::unwrap_used))]
//! Reads and writes [`cadmpeg_ir::CadIr`] documents as ISO 10303-21 STEP Part
//! 21 exchange structures for AP203, AP214, and AP242.
//!
//! <!-- generated: capability step -->
//! Support: L9 ([ladder](https://github.com/cadmpeg/cadmpeg/blob/main/docs/format-support.md#step-part-21)).
//! <!-- /generated: capability step -->
//!
//! [`StepCodec`] emits the application protocol selected through
//! [`cadmpeg_ir::codec::write::Encoder::plan`]. It writes product and representation context,
//! connected exact shape, product occurrences, tessellation, presentation,
//! and PMI when the target schema carries those domains.
//!
//! # Export workflow
//!
//! Construct or decode a [`cadmpeg_ir::CadIr`], configure [`StepCodec`], and
//! select a target from the codec's encoder catalog. Planning validates the
//! request and returns the bytes with the export report.
//!
//! Review [`cadmpeg_ir::report::export::ExportReport::losses`] before retaining output. Opaque
//! records, source attributes, unsupported
//! procedural definitions, and target-schema incompatibilities are reported or
//! rejected rather than silently discarded. Body and face colors become
//! per-face `STYLED_ITEM` presentation; direct geometry and tessellation
//! bindings retain their native presentation targets.
//!
//! Coordinates are emitted unchanged under a millimetre length-unit context.
//! Callers must convert non-millimetre geometry before export. Analytic curves
//! and surfaces map to their corresponding STEP carriers. Rational and
//! non-rational NURBS use the `*_WITH_KNOTS` entities.
