Trait ToolExecutor 

pub trait ToolExecutor: Send + Sync {
    // Required method
    fn execute<'life0, 'life1, 'async_trait>(
        &'life0 self,
        call: &'life1 ToolCall,
    ) -> Pin<Box<dyn Future<Output = Result<String, String>> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait,
             'life1: 'async_trait;
}

Runs one tool call and reports its result (issue #665).

A tool-level failure is Err(String), not a failed loop: the string is fed back to the model as a ToolResult::error, and the model may recover — try again, try another tool, or answer directly.

Required Methods

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

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

Runs call and returns the text to show the model.

Errors

Returns the error text to feed back to the model when the tool itself fails. This is not a failure of the loop.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
