impl Default for RenderScreenTool

fn default() -> Self

Returns the “default value” for a type.

impl Tool for RenderScreenTool

fn name(&self) -> &str

fn description(&self) -> &str

fn parameters_schema(&self) -> Option<Value>

fn execute<'life0, 'async_trait>( &'life0 self, _ctx: Arc<dyn ToolContext>, args: Value, ) -> Pin<Box<dyn Future<Output = Result<Value>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

fn enhanced_description(&self) -> String

Returns an enhanced description that may include additional notes. For long-running tools, this includes a warning not to call the tool again if it has already returned a pending status. Default implementation returns the base description.

fn is_long_running(&self) -> bool

Indicates whether the tool is a long-running operation. Long-running tools typically return a task ID immediately and complete the operation asynchronously.

fn response_schema(&self) -> Option<Value>

fn required_scopes(&self) -> &[&str]
