How to get the EGID of the current entity when iterating through queried entities?

[rettoph]

Ultimately Im hoping there's a way to identify which entity the component currently belongs to, something theoretically like so:

LocalFasterReadOnlyList<ExclusiveGroupStruct> groups = this.entitiesDB.FindGroups<Tree>();
foreach (var ((trees, count), groupId) in this.entitiesDB.QueryEntities<Tree>(groups))
{
    for (uint i= 0; i< count; i++)
    {
        // Does the index map to the egid's entityId?
        EGID entityId = new EGID(i, groupId);
    }
}

the entity ID of an entity is user chosen so in theory this would work if you choose to follow that logic. However what you wrote is not guaranteed, to know the id of the entity you need to change the deconstruction of the query to:

foreach (var ((trees,  entitiesID, count), groupId) in this.entitiesDB.QueryEntities<Tree>(groups))
{
    for (uint i= 0; i< count; i++)
    {
        EGID entityId = new EGID(entitiesID[i], groupId);
    }
}

so it's engine to add an extra parameter in the deconstruction
