Struct NamespacedCache 

pub struct NamespacedCache<C> { /* private fields */ }

Cache decorator that prefixes every id with a fixed namespace.

Implementations

impl<C: Cache> NamespacedCache<C>

pub fn new(inner: C, prefix: impl Into<String>) -> Self

Wrap inner, prefixing every id with prefix (e.g. "stack-a::").

Trait Implementations

impl<C: Cache> Cache for NamespacedCache<C>

fn last_record<'life0, 'life1, 'async_trait>( &'life0 self, id: &'life1 ActionId, ) -> Pin<Box<dyn Future<Output = Option<BuildRecord>> + Send + 'async_trait>>

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

Forwarded explicitly rather than left to the trait’s default body, which would route through Cache::last_build and silently drop a timestamp the inner backend actually has. This decorator is the federation-over-shared-Neo4j path — exactly where knowing when a sibling machine built something is the point.

fn last_build<'life0, 'life1, 'async_trait>( &'life0 self, id: &'life1 ActionId, ) -> Pin<Box<dyn Future<Output = Option<BuildEvent>> + Send + 'async_trait>>

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

Last recorded event for id, or None if the action has never run.

fn record<'life0, 'async_trait>( &'life0 mut self, event: BuildEvent, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

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

Persist event. After success, Self::last_build for the event’s id must return this event.

fn record_batch<'life0, 'async_trait>( &'life0 mut self, events: Vec<BuildEvent>, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

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

Persist events atomically — either every event lands or none.
