Struct ToolConfig 

pub struct ToolConfig {
    pub max_usage_count: Option<u32>,
    pub result_as_answer: bool,
    /* private fields */
}

Configuration that wraps a Tool to add usage limits and short-circuit behaviour.

Fields

max_usage_count: Option<u32>

If Some(n), the tool is disabled after n successful calls.

result_as_answer: bool

If true, the tool’s output is used directly as the final answer, bypassing further LLM reasoning in the agent loop.

Implementations

impl ToolConfig

pub fn new(tool: Arc<dyn Tool>) -> Self

Wrap a tool with default configuration (no usage limit, no result-as-answer).

pub fn with_max_usage(self, n: u32) -> Self

Set the maximum number of times this tool may be called before it is disabled.

pub fn with_result_as_answer(self) -> Self

Mark this tool so that its output is treated as the final agent answer.

pub fn is_exhausted(&self) -> bool

Returns true when the tool has hit its usage cap.
