Function notmuch_sys::notmuch_database_compact

pub unsafe extern fn notmuch_database_compact(path: *const c_char,
                                              backup_path: *const c_char,
                                              status_cb: Option<extern fn(_: *const c_char, _: *mut c_void)>,
                                              closure: *mut c_void)
                                              -> notmuch_status_t

Compact a notmuch database, backing up the original database to the given path.

The database will be opened with notmuch_database_mode_t::READ_WRITE during the compaction process to ensure no writes are made.

If the optional callback function 'status_cb' is non-NULL, it will be called with diagnostic and informational messages. The argument 'closure' is passed verbatim to any callback invoked.
