Struct AgentLoopBuilder 

pub struct AgentLoopBuilder<P: Provider, C: ContextStrategy> { /* private fields */ }

Builder for constructing an AgentLoop with optional configuration.

Created via AgentLoop::builder. Only provider and context are required; everything else has sensible defaults.

Example

let agent = AgentLoop::builder(provider, context)
    .tools(tools)
    .system_prompt("You are a helpful assistant.")
    .max_turns(10)
    .build();

Implementations

impl<P: Provider, C: ContextStrategy> AgentLoopBuilder<P, C>

pub fn tools(self, tools: ToolRegistry) -> Self

Set the tool registry.

pub fn config(self, config: LoopConfig) -> Self

Set the full loop configuration.

pub fn system_prompt(self, prompt: impl Into<SystemPrompt>) -> Self

Set the system prompt (convenience for setting config.system_prompt).

pub fn max_turns(self, max: usize) -> Self

Set the maximum number of turns (convenience for setting config.max_turns).

pub fn parallel_tool_execution(self, parallel: bool) -> Self

Enable parallel tool execution (convenience for setting config.parallel_tool_execution).

pub fn usage_limits(self, limits: UsageLimits) -> Self

Set usage limits for the loop (token budgets, request/tool call caps).

pub fn hook<H: ObservabilityHook + 'static>(self, hook: H) -> Self

Add an observability hook.

pub fn durability<D: DurableContext + 'static>(self, durable: D) -> Self

Set the durable context for crash-recoverable execution.

pub fn build(self) -> AgentLoop<P, C>

Build the AgentLoop.
