Enum ToolError 

pub enum ToolError {
    NotFound(String),
    InvalidInput(String),

    ModelRetry(String),
}

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<ToolError> for LoopError

fn from(source: ToolError) -> Self

Converts to this type from the input type.
