Struct brane_cli::planner::OfflinePlanner

source ·
pub struct OfflinePlanner {
    pub results: Arc<Mutex<HashMap<String, String>>>,
    /* private fields */
}
Expand description

The planner is in charge of assigning locations to tasks in a workflow. This one is very simple, assigning ‘localhost’ to whatever it sees.

Fields§

§results: Arc<Mutex<HashMap<String, String>>>

The results we planned last time (or whatever).

Implementations§

source§

impl OfflinePlanner

source

pub fn new( data_index: Arc<DataIndex>, results: Arc<Mutex<HashMap<String, String>>>, ) -> Self

Constructor for the OfflinePlanner.

§Arguments
  • data_index: The DataIndex that is used to resolve datasets at plantime.
  • results: A map of results to where they are, which we planned last time around.
§Returns

A new OfflinePlanner instance.

source

pub fn plan_data( name: &DataName, avail: &mut Option<AvailabilityKind>, dindex: &Arc<DataIndex>, results: &HashMap<String, String>, deferred: bool, ) -> Result<(), PlanError>

Plans the given task offline.

§Arguments
  • name: The name of the dataset or intermediate result, as a DataName (so we can distinguish between the two).
  • avail: The availability for this dataset that we will be updating.
  • dindex: The DataIndex we use to see what datasets are actually available where.
  • results: The map of results that are known in this workflow.
  • deferred: If true, then will not error if we failed to find a result yet (its declaration might come later, in that case).
§Returns

Nothing, but does change the dataset’s availability.
