Trait ToolHandler 

pub trait ToolHandler: Send + Sync {
    // Required method
    fn handle<'life0, 'async_trait>(
        &'life0 self,
        args: Value,
        extra: RequestHandlerExtra,
    ) -> Pin<Box<dyn Future<Output = Result<Value>> + Send + 'async_trait>>

    // Provided method
    fn metadata(&self) -> Option<ToolInfo> { ... }
}

Handler for tool execution.

Required Methods

fn handle<'life0, 'async_trait>( &'life0 self, args: Value, extra: RequestHandlerExtra, ) -> Pin<Box<dyn Future<Output = Result<Value>> + Send + 'async_trait>>

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

Handle a tool call with the given arguments.

Provided Methods

fn metadata(&self) -> Option<ToolInfo>

Get tool metadata including description and schema. Returns None to use default empty metadata.
