Module executor 

Agent base traits and executor implementation.

Structs

AgentExecutor

Agent executor.

BudgetConfig

Hard budget for the agent control loop. A None field means that item is unlimited.

CompactionConfig

Compaction configuration: trigger + strategy + safety floor.

FileMemoryTool

An Arc<dyn BaseTool> adapter over a FileMemoryStore, exposing the store’s ops as a single string-in/string-out tool for the agent loop.

Enums

AgentError

Agent error types.

BudgetExceeded

Details of a budget over-limit.

CompactionStrategy

How to compact. All strategies drop the oldest turns and keep at least CompactionConfig::min_recent_turns recent ones.

CompactionTrigger

When to compact. Checked before every plan() round.

Traits

BaseAgent

Base Agent trait.

Functions

estimate_step_tokens

Token estimate for one step: ~4 bytes per token over the serialized step (tool name + input + observation). Providers that do not report per-step usage leave no better signal — this mirrors the byte-length fallback used elsewhere (TokenTrackingLLM, get_num_tokens).

mount

Convenience: builds and mounts as a boxed BaseTool (Err when the root dir can’t be set up).
