Crate zerodds_idl_csharp 

IDL4 → C# 12.0 Source-Code-Generator (OMG IDL4-CSharp-Mapping, formal/2024-12-01).

Crate zerodds-idl-csharp — Foundation des Sprach-Bindings (Cluster C5.3-a).

Safety classification: SAFE (std-only). Reines Build-Zeit-Tool — forbid(unsafe_code), kein no_std-Use-Case.

Scope (C5.3-a / Phase 3.1-3.3)

• Phase 3.1: Header-Layout (#nullable enable, using, namespace).
• Phase 3.2: Primitive-Mapping (boolean → bool, octet → byte, char/wchar → char, short → short, ushort → ushort, long → int, ulong → uint, long long → long, ulong long → ulong, float/double, string → string).
• Phase 3.3: Aggregate-Types — struct → record class mit init-only Properties, enum → enum, union → discriminated record, typedef → record class-Wrapper (Spec-konformes file-scoped using-alias kommt mit C5.3-b), sequence → IList<T>, array → T[], inheritance → record class : Parent.

C5.3-b additions (this revision)

• ISequence<T> / IBoundedSequence<T> runtime contract (see runtime/Omg.Types.cs); codegen emits these instead of bare IList<T>.
• Annotation-Bridge @key|@id|@optional|@must_understand|@external on members, @nested|@extensibility(...) on types — emitted as C# attributes from Omg.Types.
• ITopicType<T> marker on every top-level (non-@nested) struct.

Bewusst nicht im Crate

• Phase 3.4: DDS-CSharp-Integration (P/Invoke zu Rust-Core).
• Time/Duration/Status/QoS/Listener-Codegen.
• File-scoped namespace + using <Alias> = <Type>; Top-Level-Form.
• Bitset/Bitmask/Map/Fixed/Any/Interface/Valuetype.

Beispiel

use zerodds_idl::config::ParserConfig;
use zerodds_idl_csharp::{generate_csharp, CsGenOptions};

let ast = zerodds_idl::parse(
    "module M { struct S { long x; }; };",
    &ParserConfig::default(),
)
.expect("parse");
let cs = generate_csharp(&ast, &CsGenOptions::default()).expect("gen");
assert!(cs.contains("namespace M"));
assert!(cs.contains("record class S"));
