1//! Reviewed KNX datapoint-type catalogue as const data.
2//!
3//! The catalogue is the single internal authority for source-derived
4//! declarative facts about datapoint types: identifiers, official names,
5//! transmitted widths, field decompositions, ranges, resolutions, code
6//! tables, named bit layouts, special values, validity associations,
7//! cross-field relations, context requirements and group-transport
8//! eligibility. Consumers read these facts here instead of interpreting
9//! the specification independently.
10//!
11//! The data under [`generated`] is produced by the `knx-data-gen` tool from
12//! reviewed structured input. It is committed, deterministic, and never
13//! edited by hand; the reviewed input is the authority over the generated
14//! output.
15//!
16//! The schema types here are open data records - public fields, no
17//! constructors - because they state declarations rather than enforce
18//! invariants; the validated primitives with sealed fields and checked
19//! constructors live in the crates that own behavior.
