Struct IncrementalVacuumSettings

pub struct IncrementalVacuumSettings {
    pub largest_root_btree_page: LargestRootBtreePage,
    pub incremental_vacuum_mode: IncrementalVacuumMode,
}

Incremental vacuum settings (8 Bytes)

The two 4-byte big-endian integers at offsets 52 and 64 are used to manage the auto_vacuum and incremental_vacuum modes. If the integer at offset 52 is zero then pointer-map (ptrmap) pages are omitted from the database file and neither auto_vacuum nor incremental_vacuum are supported. If the integer at offset 52 is non-zero then it is the page number of the largest root page in the database file, the database file will contain ptrmap pages, and the mode must be either auto_vacuum or incremental_vacuum. In this latter case, the integer at offset 64 is true for incremental_vacuum and false for auto_vacuum. If the integer at offset 52 is zero then the integer at offset 64 must also be zero.
