AuthorityCallId

public static class AuthorityCallId

The identity of one cross-worker call: the sending worker's index in the top 16 bits and a per-sender sequence in the low 48, the same shape as an entity NetId. Forwarding keeps the id, so every worker on the path and the reply agree on which call they mean.

Fields

SequenceBits

public const int SequenceBits = 48;

Bits of the sequence part; the worker index sits above it.

Methods

Make

public static ulong Make(ushort workerIndex, ulong sequence);

Compose a call id from the sender's worker index and its sequence number.

WorkerIndexOf

public static ushort WorkerIndexOf(ulong callId);

The worker that minted callId: where a reply goes.

SequenceOf

public static ulong SequenceOf(ulong callId);

The sequence part of callId.

InitialSequence

public static ulong InitialSequence(uint incarnation);

Where a sender's sequence starts for one run of its process: the low 16 bits of its incarnation, shifted above 32 bits of room. A worker that restarts with the same index therefore mints ids a previous run never used, and a receiver's ledger cannot mistake its first calls for duplicates of the old run's.
