Expand description

Dyn-compatible adapter for the FunctionBody trait

This is a dyn-compatible version of the FunctionBody trait.

This trait is automatically implemented for all types that implement FunctionBody.

Required Methods§

Source

fn execute<'a>( &'a self, env: &'a mut Env, ) -> Pin<Box<dyn Future<Output = Result> + 'a>>

Executes the function body in the given environment.

The implementation of this method is expected to update env.exit_status reflecting the result of the function execution.
