Struct SqliteStorage 

pub struct SqliteStorage { /* private fields */ }

Implementations

impl SqliteStorage

pub fn open(path: impl AsRef<Path>) -> Result<Self>

Open (and create if needed) the database at path.

pub fn in_memory() -> Result<Self>

A private in-memory database. Useful for tests and for a --no-persist run.

pub async fn prune_expired(&self, now: OffsetDateTime) -> Result<usize>

Delete every record whose expiry has passed.

Reads already ignore expired records; this only reclaims disk space, so it is safe to call on a schedule or never.

Trait Implementations

impl Clone for SqliteStorage

fn clone(&self) -> SqliteStorage

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SqliteStorage

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

Formats the value using the given formatter.

impl Storage for SqliteStorage

fn get<'life0, 'life1, 'async_trait>( &'life0 self, key: &'life1 StorageKey, ) -> Pin<Box<dyn Future<Output = Result<Option<Record>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Returns the record as stored, including expired ones. Callers that care about freshness go through crate::Cache.

fn put<'life0, 'life1, 'async_trait>( &'life0 self, key: &'life1 StorageKey, record: Record, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

fn delete<'life0, 'life1, 'async_trait>( &'life0 self, key: &'life1 StorageKey, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Deleting a missing key succeeds.

fn keys<'life0, 'life1, 'async_trait>( &'life0 self, namespace: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<Vec<StorageKey>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

All keys in a namespace, in unspecified order.

fn clear<'life0, 'life1, 'async_trait>( &'life0 self, namespace: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Drop every record in a namespace.

fn clear_prefix<'life0, 'life1, 'async_trait>( &'life0 self, prefix: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<usize>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Drop every record whose namespace starts with prefix, and report how many.
