Struct StoreStats

pub struct StoreStats { /* private fields */ }

Implementations

impl StoreStats

pub fn count(&self) -> u64

Total number of blocks in the store

pub fn size(&self) -> u64

Total size of blocks in the store

pub fn page_size(&self) -> u64

Page size used by the SQLite DB

pub fn used_pages(&self) -> u64

Number of used pages in the SQLite DB

Multiply this with page_size to obtain an upper bound on how much space is actually used. The value returned by size will always be smaller than this, since it only counts net block data, without overhead. A large difference suggests the need for calling vacuum.

pub fn free_pages(&self) -> u64

Number of unused pages in the SQLite DB

The DB file can be shrunk by at least this page count by calling vacuum, which often is a long-running procedure.

Trait Implementations

impl Clone for StoreStats

fn clone(&self) -> StoreStats

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StoreStats

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

Formats the value using the given formatter.

impl Default for StoreStats

fn default() -> StoreStats

Returns the “default value” for a type.

impl PartialEq for StoreStats

fn eq(&self, other: &StoreStats) -> 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.
