Struct Calculator 

pub struct Calculator;

A tool that evaluates math expressions, so agents don’t do arithmetic in their heads.

The input is an expression such as (1234.5 * 3) / sqrt(2); see evaluate_expression for the syntax. Invalid expressions come back as tool errors that say what’s wrong, so the model can fix the expression and retry.

Implementations

impl Calculator

pub fn new() -> Self

Trait Implementations

impl Clone for Calculator

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Calculator

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Calculator

fn default() -> Self

Returns the “default value” for a type.

impl Tool for Calculator

fn name(&self) -> String

Returns the name of the tool.

fn description(&self) -> String

Provides a description of what the tool does and when to use it.

fn parameters(&self) -> Value

This are the parametters for OpenAi-like function call. You should return a jsnon like this one

fn run<'life0, 'async_trait>( &'life0 self, input: Value, ) -> Pin<Box<dyn Future<Output = Result<String, Box<dyn Error>>> + Send + 'async_trait>>

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

Executes the core functionality of the tool.

fn call<'life0, 'life1, 'async_trait>( &'life0 self, input: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<String, Box<dyn Error>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Processes an input string and executes the tool’s functionality, returning a Result.

fn parse_input<'life0, 'life1, 'async_trait>( &'life0 self, input: &'life1 str, ) -> Pin<Box<dyn Future<Output = Value> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Parses the input string, which could be a JSON value or a raw string, depending on the LLM model.
