Prompt errors

Variants

CompletionError(CompletionError)

Something went wrong with the completion

ToolError(ToolSetError)

There was an error while using a tool

ToolServerError(Box<ToolServerError>)

There was an issue while executing a tool on a tool server

MaxTurnsError

The LLM tried to call too many tools during a multi-turn conversation. To fix this, you may either need to lower the amount of tools your model has access to (and then create other agents to share the tool load) or increase the amount of turns given in .multi_turn().

Fields

max_turns: usize

chat_history: Box<Vec<Message>>

prompt: Box<Message>

PromptCancelled

A prompting loop was cancelled.

Fields

chat_history: Vec<Message>

reason: String

UnknownToolCall

The model emitted a structured tool call for a tool Rig did not allow for the current turn.

Fields

tool_name: String

available_tools: Vec<String>

allowed_tools: Vec<String>

chat_history: Box<Vec<Message>>

Trait Implementations

impl Debug for PromptError

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

Formats the value using the given formatter.

impl Display for PromptError

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

Formats the value using the given formatter.

impl Error for PromptError

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<Box<ToolServerError>> for PromptError

fn from(source: Box<ToolServerError>) -> Self

Converts to this type from the input type.

impl From<CompletionError> for PromptError

fn from(source: CompletionError) -> Self

Converts to this type from the input type.

impl From<MemoryError> for PromptError

Surface crate::memory::ConversationMemory failures through the existing CompletionError::RequestError variant so adding memory support does not require a new top-level PromptError arm in downstream exhaustive matchers.

fn from(err: MemoryError) -> Self

Converts to this type from the input type.

impl From<ToolSetError> for PromptError

fn from(source: ToolSetError) -> Self

Converts to this type from the input type.
