API Reference¶
dccd v3 is a hexagonal architecture (see Architecture): a pure domain, an async transport layer, exchange sources, storage, an application layer of operations, and thin interfaces. The reference is organised by layer — each page introduces the layer, then documents its members.
Most users only need the Client.
Client
The one-stop async facade.
Domain
Pure value objects, capabilities and transforms — no I/O.
Transport
Async HTTP, WebSocket base, rate limiter and paginators.
Sources
The Source protocols and the adapter registry.
Storage
Parquet datasets and run history.
Application
Operations, scheduler, jobs, events and config.
