Function scalar_leaf_index 

Source 
fn scalar_leaf_index(
    schema: &SchemaDescriptor,
    root_index: usize,
) -> Option<usize>
Expand description

Maps a scalar root to its physical leaf. Nested roots have no root-level statistics, even with one leaf: child null counts do not describe parents. All row groups of a file share the same schema.
