Trait Implementations

impl Cache for NoCache

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

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

Look up key; Ok(None) is a normal miss, Err is reserved for real backend faults (disk error, redb panic recovery, etc.).

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

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

Store rows under key, replacing whatever was there.

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

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

Drop every entry whose key starts with prefix. v1 callers always pass the bare cache_key — every page suffix below it goes. Implementations should accept any prefix (so finer-grained invalidation can be added later without breaking the trait).

impl Clone for NoCache

fn clone(&self) -> NoCache

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NoCache

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

Formats the value using the given formatter.

impl Default for NoCache

fn default() -> NoCache

Returns the “default value” for a type.

impl Copy for NoCache
