Module startup_library_snapshot 

Compact on-disk snapshot of library metadata (platforms + merged collections).

Used by the TUI to paint the library screen immediately on entry while a background refresh reconciles with the API. Full ROM lists remain on-demand and continue to use crate::core::cache::RomCache.

Structs

CollectionDigestEntry

Compact digest used to quickly detect collection-summary changes.

LibraryMetadataFetch

Result of a live metadata fetch (background or cold path).

Functions

build_collection_digest_from_collections

Build a lightweight digest keyed by collection identity (manual/smart/virtual).

fetch_collection_summaries

Stage-A refresh: collections summary only (manual/smart/virtual merge).

fetch_merged_library_metadata

Fetch platforms and merged collections from the API (same behavior as the former synchronous TUI main-menu path, including virtual collection timeout).

load_snapshot

Load a snapshot from disk if present and valid.

save_snapshot

Persist merged metadata for next startup.

snapshot_effective_path

Effective path to the snapshot file.
