Enum AgentError 

pub enum AgentError {
    SessionNotFound(String),
    LLM(String),
    LLMOverflow(String),
    Tool(String),
    Budget(String),
    Cancelled,
}

Errors that can occur during agent operations

Variants

SessionNotFound(String)

Session with the specified ID was not found

LLM(String)

Error from LLM provider (API error, network error, etc.)

LLMOverflow(String)

LLM request exceeded provider context/input limits and requires host-side overflow recovery before retry.

Tool(String)

Error during tool execution

Budget(String)

Token budget exceeded error

Cancelled

Agent execution was cancelled by user

Implementations

impl AgentError

pub fn is_cancelled(&self) -> bool

Returns true if this error represents a user-initiated cancellation.

Prefer this over substring-matching the error message: a reworded or localized message must not silently break cancellation/terminal-status logic.

Trait Implementations

impl Debug for AgentError

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

Formats the value using the given formatter.

impl Display for AgentError

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

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.
