Enum AgentError 

pub enum AgentError {
    Llm(String),
    ToolNotFound(String),
    ResponseParse(String),
    Serde(Error),
    Other(String),
}

Errors surfaced by Temporal activities and the agent loop.

Variants split along two axes: where the error originated (LLM, tool registry, parser, serde) and whether it should be retried by Temporal — see AgentError::is_retryable.

Variants

Llm(String)

Upstream LLM provider error (network, rate limit, auth, etc.).

ToolNotFound(String)

LLM returned a tool call that the worker hasn’t registered.

ResponseParse(String)

LLM response couldn’t be parsed into a crate::state::LlmResponse.

Serde(Error)

JSON ser/de failure crossing the activity boundary.

Other(String)

Catch-all for activity-side failures we don’t otherwise classify.

Implementations

impl AgentError

pub fn is_retryable(&self) -> bool

Returns true when the error is worth a Temporal retry.

Network blips, rate limits, and transient provider hiccups are retryable; missing tool registrations and parse failures are not — they indicate a code bug, not a transient condition.

Trait Implementations

impl Debug for AgentError

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

Formats the value using the given formatter.

impl Display for AgentError

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

Formats the value using the given formatter.

impl Error for AgentError

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>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<Error> for AgentError

fn from(source: Error) -> Self

Converts to this type from the input type.
