Struct re_query::LatestAtResults

source · 
pub struct LatestAtResults {

    pub query: LatestAtQuery,
    pub compound_index: (TimeInt, RowId),
    pub components: IntMap<ComponentName, UnitChunkShared>,
}
Expand description

Results for a latest-at query.

Use LatestAtResults::get and/or LatestAtResults::get_required in order to access the results for each individual component.

Fields§

§entity_path: EntityPath

The associated [EntityPath].

§query: LatestAtQuery

The query that yielded these results.

§compound_index: (TimeInt, RowId)

The compound index of this query result.

A latest-at query is a compound operation that gathers data from many different rows. The index of that compound result corresponds to the index of most the recent row in all the sub-results, as defined by time and row-id order.

§components: IntMap<ComponentName, UnitChunkShared>

Results for each individual component.

Each [UnitChunkShared] MUST always contain the corresponding component.
