RetryPolicy

Struct RetryPolicy 

Source
pub struct RetryPolicy { /* private fields */ }
Expand description

重试策略配置。

max_attempts 表示总尝试次数(初始执行 + 重试),与主流 SDK 语义一致:

  • max_attempts = 1 → 不重试,只执行一次
  • max_attempts = 3 → 初始执行 + 最多 2 次重试

Implementations§

Source§

impl RetryPolicy

Source

pub fn new(max_attempts: u32, backoff: BackoffStrategy) -> Self

Source

pub fn max_attempts(&self) -> u32

获取总尝试次数。

Source

pub fn backoff(&self) -> &BackoffStrategy

获取退避策略引用。

Source

pub async fn execute_with_retry( &self, tool_fn: &ToolFn, args: &Value, ) -> ToolResult

执行工具函数并自动重试可重试的错误。

max_attempts = 总尝试次数(初始执行 + 重试),与 AWS SDK / reqwest 等语义一致。 执行链:ToolUseLoop → ToolExecutor → RetryPolicy → tool_fn()

Source

pub async fn execute_with_retry_and_emission( &self, tool_fn: &ToolFn, args: &Value, tx: &Sender<AgentEvent>, tool_call_id: &str, ) -> ToolResult

执行工具函数并自动重试可重试的错误,同时发射 Retry 事件。

与 [execute_with_retry] 的区别:每次重试前通过 tx 发射 AgentEvent::Retry
