Struct DataControllerResponse 

Source 
pub struct DataControllerResponse<DC>
where
    DC: DataController,
{
    pub op: DataControllerOp,
    pub update: Option<DC::CacheUpdate>,
}
Expand description

The response that the cache controller receives from the data controller after processing a new/change/delete/access request.

Fields§

§op: DataControllerOp

The operation that the data controller suggests to perform with the value associated with the processed request.

§update: Option<DC::CacheUpdate>

The update record produced by the data controller. If it is not None then the cache controller must put it into the update pool and will later pass it into the DataController::write_back() method.
