Struct LongRunningFunctionTool 

pub struct LongRunningFunctionTool { /* private fields */ }

Wraps a ToolFunction and marks it as long-running.

The wrapper appends the long-running instruction to the inner tool’s description so the LLM knows not to re-invoke it while a previous call is still in progress. All other trait methods delegate directly to the inner tool.

Implementations

impl LongRunningFunctionTool

pub fn new(inner: Arc<dyn ToolFunction>) -> Self

Create a new LongRunningFunctionTool wrapping the given inner tool.

pub fn is_long_running(&self) -> bool

Returns true — this tool is always considered long-running.
