CborSerializer

Defined in: src/serialization/CborSerializer.ts:25

CBOR serializer — compact binary format, used by default for system messages (heartbeats, gossip, handoff) and available for any user type that benefits from smaller payloads than JSON.

It carries the SAME rich types as JsonSerializer — Date, Map, Set, BidirectionalMap, bigint, Uint8Array, RegExp, URL, Error, every typed array, NaN/Infinity/-0 — as real instances, just in compact binary rather than tagged JSON text. The two are asserted equal by tests/unit/serialization/RichTypeParity.test.ts; they used to disagree, silently and lossily, until #1036.

One deliberate difference: undefined is carried natively (CBOR simple value 23), including as an object property, where JsonSerializer rejects it outright. That makes this the more permissive of the two.

Manifests are not used by the CBOR serializer itself — the caller is expected to round-trip compatible shapes. A user CLASS still decodes to a plain object unless the framework tags it; register a dedicated serializer via SerializationExtension for that.

Constructor

new CborSerializer(): CborSerializer

Returns

CborSerializer

Properties

id

readonly id: 2 = 2

Defined in: src/serialization/CborSerializer.ts:26

Stable identifier that is embedded in every frame. Numbers 1..99 are reserved for the actor-ts built-ins (JSON=1, CBOR=2). User-defined serializers SHOULD use IDs ≥ RESERVED_SERIALIZER_IDS_BELOW.

Implementation of

Serializer.id

includesManifest

readonly includesManifest: false = false

Defined in: src/serialization/CborSerializer.ts:28

True when this serializer is willing to encode the given value.

Implementation of

Serializer.includesManifest

name

readonly name: "cbor" = 'cbor'

Defined in: src/serialization/CborSerializer.ts:27

Human-readable name, surfaced in diagnostics.

Implementation of

Serializer.name

Methods

fromBinary()

fromBinary(bytes, _manifest): unknown

Defined in: src/serialization/CborSerializer.ts:36

Decode from binary. manifest is whatever was produced on the other side (or ” when the serializer does not use one).

Parameters

bytes

Uint8Array

_manifest

string

Returns

unknown

Implementation of

Serializer.fromBinary

manifest()

manifest(_obj): string

Defined in: src/serialization/CborSerializer.ts:30

Return a tag describing the concrete type of obj so the decoder knows how to reconstruct it. Typical values: class name, event ID, “map”, “null”, etc. May return an empty string for serializers that don’t need a manifest.
