Struct AgentRunError 

pub struct AgentRunError {
    pub source: Error,
    pub restore_state: Option<Value>,
}

Error wrapper carrying the agent’s exported state alongside the original provider error.

Implementing std::error::Error + Display makes it compatible with anyhow::Error::downcast_ref. The source() returns the original error so classify’s cause-chain walk still works.

Fields

source: Error

The original error (e.g. from run_streaming()).

restore_state: Option<Value>

The agent’s exported state at the point of failure, if available. None when the agent failed before accumulating any state (e.g. model-resolution error before the first LLM call).

Implementations

impl AgentRunError

pub fn wrap(source: Error, restore_state: Option<Value>) -> Self

Wrap a streaming error, capturing the agent’s exported state.

Trait Implementations

impl Debug for AgentRunError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for AgentRunError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for AgentRunError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)
