Crate zerodds_corba_cos_transactions 

Crate zerodds-corba-cos-transactions. Safety classification: STANDARD.

OMG Object Transaction Service (OTS / CosTransactions) 1.4 (formal/2003-09-02) — pure-Rust no_std + alloc, forbid(unsafe_code). The OTS brings distributed transactions (ACID) into the CORBA model and is the core lever for the “drop-in for legacy finance systems” migration: 2-phase commit across multiple servers, with transaction-context propagation via the GIOP service context TransactionService (id = 0).

Implements:

• otid_t (§ OTS Appendix A) — the cross-ORB transaction identifier; byte-exact CDR codec (otid).
• PropagationContext + TransactionService service context (id = 0) — transaction-context propagation over GIOP (propagation).
• 2-phase commit protocol (prepare/commit/rollback/ commit_one_phase/forget) with a vote-driven state machine, incl. read-only optimization + one-phase commit (two_phase).
• Current / Coordinator / Terminator / Control — the OTS orchestration interfaces as Rust types (transaction).
• TransactionLog / RecoveryCoordinator (§10.3.7) — durability: the commit decision is force-written before phase 2; a restart resolves in-doubt transactions as presumed-abort (recovery).

Spec: OMG Transaction Service 1.4. Real-Time CORBA + CosTrading are separate (Trading subordinate, RT-CORBA covered via DDS-QoS).
