Struct FilterStatsResult

    pub count: u64,
    pub count_capped: bool,

    pub by_type: HashMap<String, u64>,

}

Filtered aggregate stats — count + size + per-type breakdown reflecting the active search/filter. One round-trip: COUNT + SUM + GROUP BY in SQL.

Fields

count: u64

count_capped: bool

True when count is a floor — per-type breakdown and bytes were skipped.

total_bytes: u64

by_type: HashMap<String, u64>

bytes_by_type: HashMap<String, u64>

total_unfiltered: u64

size_buckets: Vec<u64>

Audio-only: file-size histogram (6 buckets, same thresholds as heatmap-dashboard.js).

bpm_buckets: Vec<u64>

Audio-only: BPM histogram (34 bins, 50–220 step 5) for heatmap; empty for non-audio.

bpm_analyzed_count: u64

Audio-only: library rows with bpm IS NOT NULL in the filtered scope.

key_counts: HashMap<String, u64>

Audio-only: key_name → count (top keys) for heatmap key card.

key_analyzed_count: u64

top_folders: Vec<TopFolderRow>

Audio-only: top directory groups (first 3 path segments), sorted by count. Always serialized (even []) so the frontend can tell DB aggregates from a missing field.
