Crate anda_engine 

Runtime implementation for the Anda agent framework.

anda_engine turns the traits and data contracts from anda_core into a runnable agent engine. It provides the execution context, model routing, storage, hooks, memory tools, remote engine integration, and built-in extensions used by Anda agents.

Main modules

• engine: engine construction, agent execution, tool calls, and remote engine metadata.
• context: runtime contexts passed to agents and tools, including cache, storage, HTTP, Web3, cancellation, and state features.
• model: model provider adapters and label-based model routing.
• extension: reusable tools such as filesystem, shell, fetch, notes, skills, todos, extraction, and search.
• memory: persistent conversation and resource memory backed by AndaDB and the Cognitive Nexus.
• store: object storage abstraction used by engine contexts.

Feature flags

• sandbox: enables the sandboxed shell runtime backed by boxlite.
• full: enables all optional runtime features currently provided by this crate.

Functions

json_convert_rfc3339_timestamp

Converts each JSON object’s timestamp field from Unix milliseconds to RFC 3339.

json_set_unix_ms_timestamp
