Struct DiffReport 

pub struct DiffReport {
    pub added: Vec<TileChange>,
    pub removed: Vec<TileChange>,
    pub changed: Vec<TileChange>,
    pub unchanged_count: u64,
}

Full per-tile diff between two PMTiles archives.

Each Vec is sorted by ascending tile_id. unchanged_count counts tiles present in both archives whose FNV-1a content hashes match.

Fields

added: Vec<TileChange>

Tiles present in the new archive but absent in the old archive.

removed: Vec<TileChange>

Tiles present in the old archive but absent in the new archive.

changed: Vec<TileChange>

Tiles present in both with differing FNV-1a content hashes.

unchanged_count: u64

Tiles present in both with identical FNV-1a content hashes.

Implementations

impl DiffReport

pub fn total_changes(&self) -> usize

Total number of changes (added + removed + changed).

pub fn total_added_bytes(&self) -> usize

Sum of byte lengths of all tiles in the Self::added list.

pub fn total_removed_bytes(&self) -> usize

Sum of byte lengths of all tiles in the Self::removed list.

pub fn changed_byte_delta(&self) -> i64

Net byte delta of changed tiles (new total minus old total).

A positive value means changed tiles grew on average; a negative value means they shrank.

pub fn is_empty(&self) -> bool

Returns true when there are no added, removed, or changed tiles.
