Trait for implementing custom schedulers

Required Methods§

Source

fn schedule<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, task: &'life1 Task, nodes: &'life2 [Node], ) -> Pin<Box<dyn Future<Output = Result<NodeId, PolarisError>> + Send + 'async_trait>>
where 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, Self: 'async_trait,

Schedule a task on one of the available nodes

§Arguments
  • task - The task to schedule
  • nodes - Available nodes for scheduling
§Returns

Returns the selected node ID, or an error if scheduling fails

Source
