Expand description

Async interface for task functions that operate on messages

§Usage

Implement this trait for custom processing logic. The function receives:

  • Mutable access to the message being processed (no cloning needed!)
  • Pre-parsed function configuration
  • Reference to the DataLogic instance for JSONLogic evaluation

§Performance Note

This trait works directly with &mut Message without any cloning. The message is passed by mutable reference throughout the async execution, ensuring zero-copy operation for optimal performance.

Required Methods§

Source

fn execute<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, message: &'life1 mut Message, config: &'life2 FunctionConfig, datalogic: Arc<DataLogic>, ) -> Pin<Box<dyn Future<Output = Result<(usize, Vec<Change>)>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Execute the function on a message with pre-parsed configuration

§Arguments
  • message - The message to process (mutable reference, no cloning)
  • config - Pre-parsed function configuration
  • datalogic - Reference to DataLogic instance for JSONLogic evaluation
§Returns
  • Result<(usize, Vec<Change>)> - Result containing status code and changes, or error
