Enum AgentError 

#[non_exhaustive]
pub enum AgentError {
    OutputParsingError(String),
    ToolNotFound(String),
    ToolExecutionError(String),
    MaxIterationsReached,
    BudgetExceeded(BudgetExceeded),
    Resume(String),
    Other(String),
}

Agent error types.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

OutputParsingError(String)

Output parsing error.

ToolNotFound(String)

Tool not found.

ToolExecutionError(String)

Tool execution error.

MaxIterationsReached

Max iterations reached.

BudgetExceeded(BudgetExceeded)

Budget exceeded (approval/budget gate §4.2). Callers catch it to distinguish a “budget stop” from “the model did not converge”.

Resume(String)

Cross-process resume (§4.2): checkpoint read / write / restore failed.

Other(String)

Other error.

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<AgentError> for LcelError

Allow AgentError to convert into LcelError.

fn from(err: AgentError) -> Self

Converts to this type from the input type.

impl From<AgentError> for PlanExecuteError

fn from(e: AgentError) -> Self

Converts to this type from the input type.
