Trait Tool 

pub trait Tool: Send + Sync {
    // Required methods
    fn raw_tools(&self) -> Vec<RawTool>;
    fn call<'life0, 'life1, 'async_trait>(
        &'life0 self,
        name: &'life1 str,
        args: Value,
    ) -> Pin<Box<dyn Future<Output = Value> + Send + 'async_trait>>
       where Self: 'async_trait,

}

Required Methods

fn raw_tools(&self) -> Vec<RawTool>

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

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

Invoke the named tool with the given arguments and return the result as a JSON value.

When using the #[tool] macro you do not implement this method yourself — the macro generates it. The generated implementation accepts any return type that implements serde::Serialize (including serde_json::Value, plain structs with #[derive(Serialize)], primitives, etc.) and converts the value to serde_json::Value automatically.
