TaskLaunchService

mlua_swarm::service::task_launch

Struct TaskLaunchService 

Source 
pub struct TaskLaunchService { /* private fields */ }
Expand description

Domain service that compiles, links, and runs a Blueprint’s flow to completion through the Engine. See the module doc for the full responsibility list.

Implementations§

Source§

impl TaskLaunchService

Source

pub fn new(engine: Engine, compiler: Compiler) -> Self

Build a service bound to one Engine and one Compiler.

Source

pub fn engine(&self) -> &Engine

The bound Engine.

Source

pub fn compiler(&self) -> &Compiler

The bound Compiler.

Source

pub async fn launch( &self, input: TaskLaunchInput, ) -> Result<TaskLaunchOutput, TaskLaunchError>

Run the Blueprint’s flow to completion and return the final ctx.

Failure paths:

  • compiler.compile failure → TaskLaunchError::Compile.
  • engine.attach failure → TaskLaunchError::Engine.
  • A Step inside flow eval producing a dispatcher error, or a sub-flow raising, → TaskLaunchError::FlowEval. There is no silent partial-success completion; failures always propagate.
