Implementations

impl AgentError

pub fn tool_execution( tool_name: impl Into<String>, message: impl Into<String>, ) -> Self

Create a new tool execution error.

pub fn parsing(output: impl Into<String>, message: impl Into<String>) -> Self

Create a new parsing error.

pub fn model(message: impl Into<String>) -> Self

Create a new model error.

pub const fn max_steps(steps: usize, max_steps: usize) -> Self

Create a new max steps error.

pub fn configuration(message: impl Into<String>) -> Self

Create a new configuration error.

pub fn internal(message: impl Into<String>) -> Self

Create a new internal 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, f: &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(err: Error) -> Self

Converts to this type from the input type.

impl From<Error> for AgentError

fn from(err: Error) -> Self

Converts to this type from the input type.
