Database configuration

Fields

columns: u32

Set number of columns. The number of columns must not be zero.

flags: OpenFlags

Set flags used to open the database

num_conns: usize

Number of connections to open

vacuum_mode: VacuumMode

Vacuum mode

repair_on_corrupt: bool

On corruption, at open or at runtime, salvage the readable rows into a fresh database, keeping the damaged files beside it

repair_check: RepairCheck

Which integrity check gates the open-time repair

repair_check_byte_limit: Option<u64>

Skip the open-time check when the database (plus WAL) is larger than this; the check reads every page, so on a large store it can hold up open for a long time, and runtime repair still covers what it would have caught. None checks regardless of size.

on_repair: Option<RepairCallback>

Called with a report every time a repair runs
