Trait RunHandler 

pub trait RunHandler: Send + Sync {
    // Required methods
    fn run_type(&self) -> &str;
    fn handle<'life0, 'life1, 'life2, 'life3, 'async_trait>(
        &'life0 self,
        task_name: &'life1 str,
        run_config: &'life2 Value,
        input: &'life3 Value,
    ) -> Pin<Box<dyn Future<Output = WorkflowResult<Value>> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait,
             'life1: 'async_trait,
             'life2: 'async_trait,
             'life3: 'async_trait;
}

Handler for run task types that require custom implementations.

Implement this trait to provide support for run types like container and script. Register handlers with WorkflowRunner::with_run_handler().

Example

use async_trait::async_trait;
use serde_json::Value;
use swf_runtime::{RunHandler, WorkflowResult};

struct ContainerRunHandler;

#[async_trait]
impl RunHandler for ContainerRunHandler {
    fn run_type(&self) -> &str { "container" }

    async fn handle(
        &self,
        task_name: &str,
        run_config: &Value,
        input: &Value,
    ) -> WorkflowResult<Value> {
        // Implement container run logic here
        Ok(serde_json::json!({ "exitCode": 0 }))
    }
}

Required Methods

fn run_type(&self) -> &str

Returns the run type this handler supports (e.g., “container”, “script”)

fn handle<'life0, 'life1, 'life2, 'life3, 'async_trait>( &'life0 self, task_name: &'life1 str, run_config: &'life2 Value, input: &'life3 Value, ) -> Pin<Box<dyn Future<Output = WorkflowResult<Value>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, 'life3: 'async_trait,

Executes the run with the given configuration and input.
