GraphBinary Serialization

Binary serialization format for graph traversal components.

Format

Each value is serialized as:

┌──────────┬───────────┬────────────┬─────────┐
│ type_code│ type_info │ value_flag │  value  │
│  (1 byte)│ (optional)│  (1 byte)  │(variable│
└──────────┴───────────┴────────────┴─────────┘

Type Codes

• 0x00: Custom
• 0x01: Int32
• 0x02: Int64
• 0x03: Float
• 0x04: Double
• 0x05: String
• 0x06: List
• 0x07: Map
• 0x08: Set
• 0x09: UUID
• 0x0A: Edge
• 0x0B: Vertex
• 0x0C: Path
• 0x0D: Property
• 0x0E: Traverser
• 0x0F: Bytecode (traversal plan)
• 0x10: Binding
• 0x11: Step (custom step type)

Value Flags

• 0x00: Value present
• 0x01: Null value
• 0x02: Bulk value (for Traverser)
