Struct IndexFilter 

pub struct IndexFilter {
    pub pkg_type: Option<i8>,
    pub repo: Option<String>,
}

Selective sub-index filter: keep only sub-indexes whose manifest entry matches. A None field matches anything, so IndexFilter::default() reads the whole archive (what read_znippy_index does). Filtering happens at the (pkg_type, repo) sub-index granularity — whole Arrow IPC streams are skipped, never read — so a selective extract touches only the matching rows.

Fields

pkg_type: Option<i8>

Keep only this package-type discriminant (ManifestEntry::pkg_type).

repo: Option<String>

Keep only this repo (ManifestEntry::repo).
