    metadata: &ParquetMetaData,
    column_index_policy: PageIndexPolicy,

Arguments

• metadata - The footer metadata describing the page index locations.

• offset_index_policy - The policy for handling offset index parsing (e.g., Required, Optional, Skip).
• column_index_mask - The row groups and leaf columns whose column indexes are parsed. Ignored when column_index_policy is PageIndexPolicy::Skip.
• offset_index_mask - The row groups and leaf columns whose offset indexes are parsed. Ignored when offset_index_policy is PageIndexPolicy::Skip.
• bytes - The byte slice containing the page index data.
• start_offset - The offset where bytes begin in the file.
