Struct MaintenanceOptions 

pub struct MaintenanceOptions {
    pub run_optimize: bool,
    pub incremental_vacuum_pages: u32,
    pub freelist_threshold_pages: u32,
    pub wal_checkpoint: bool,
}

Which steps a maintenance pass performs and the thresholds that gate them. Default is the server’s tuning: optimize on, reclaim up to 1000 freelist pages once ≥1000 have built up (~4 MiB at a 4 KiB page), passive checkpoint on.

Fields

run_optimize: bool

Run PRAGMA optimize to refresh stale planner statistics.

incremental_vacuum_pages: u32

Max freelist pages to return to the OS per pass (the N in incremental_vacuum(N)). 0 disables the vacuum step.

freelist_threshold_pages: u32

Only run the vacuum step once the freelist has at least this many pages — so a quiet database is left untouched and the step is not churned for a handful of pages.

wal_checkpoint: bool

Take a PRAGMA wal_checkpoint(PASSIVE) to bound WAL growth.

Trait Implementations

impl Clone for MaintenanceOptions

fn clone(&self) -> MaintenanceOptions

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MaintenanceOptions

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for MaintenanceOptions

fn default() -> MaintenanceOptions

Returns the “default value” for a type.

impl PartialEq for MaintenanceOptions

fn eq(&self, other: &MaintenanceOptions) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
