Enum StepResult 

pub enum StepResult {
    Stop(String),
    Toolcalled(Option<String>),
}

The result of running one agent step.

Variants

Stop(String)

The model produced a final assistant message and did not request any further tool calls. The wrapped string is that assistant message.

Toolcalled(Option<String>)

The model issued one or more tool calls. The wrapped value is the optional assistant text emitted alongside the tool calls (some providers include reasoning or commentary in this field, others leave it empty, hence the Option).

Implementations

impl StepResult

pub fn assistant_message(&self) -> Option<&String>

Returns the assistant text associated with this step, if any.

For StepResult::Stop this is always the final message; for StepResult::Toolcalled it is the optional text the model attached to the tool-call response.

pub fn did_tool_call(&self) -> bool

Returns true if the model requested tool calls in this step.

pub fn did_stop(&self) -> bool

Returns true if the model finished its turn with a final message.
