Enum LoopError 

pub enum LoopError {
    Provider(ProviderError),
    Tool(ToolError),
    Context(ContextError),
    MaxTurns(usize),
    HookTerminated(String),
    Cancelled,
    UsageLimitExceeded(String),
}

Errors from the agentic loop.

Variants

Provider(ProviderError)

Provider call failed.

Tool(ToolError)

Tool execution failed.

Context(ContextError)

Context management failed.

MaxTurns(usize)

Loop exceeded the configured turn limit.

HookTerminated(String)

An observability hook terminated the loop.

Cancelled

The loop was cancelled via the cancellation token.

UsageLimitExceeded(String)

A usage limit was exceeded (token budget, request limit, or tool call limit).

Trait Implementations

impl Debug for LoopError

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

Formats the value using the given formatter.

impl Display for LoopError

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

Formats the value using the given formatter.

impl Error for LoopError

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.
