Struct MaterializedViewCache 

pub struct MaterializedViewCache { /* private fields */ }

Cache for materialized views

Implementations

impl MaterializedViewCache

pub fn new() -> Self

Create a new materialized view cache

pub fn register(&mut self, def: MaterializedViewDef)

Register a view definition

pub fn claim_due_at(&mut self, now: Instant) -> Vec<String>

Atomically claim the set of views due for periodic refresh at the given logical instant. Returned views have their last_refresh pre-advanced to now so a concurrent caller on the same tick sees them as not-due (the contract requested by the “exactly once per tick, no duplicates” acceptance criterion in issue #583 slice 10).

pub fn record_refresh_success( &mut self, name: &str, data: Vec<u8>, row_count: u64, duration_ms: u64, at_unix_ms: u64, )

Record a successful refresh — updates cached data, row count, duration, wall-clock timestamp, and clears any prior error.

pub fn record_refresh_failure( &mut self, name: &str, error: String, duration_ms: u64, at_unix_ms: u64, )

Record a refresh failure — captures the error string and duration but leaves data / current_row_count intact so the prior content remains readable (per acceptance criterion).

pub fn metadata(&self) -> Vec<MaterializedViewMetadata>

Per-view runtime state snapshot — feeds red.materialized_views.

pub fn get(&self, name: &str) -> Option<&[u8]>

Get view data (if not stale)

pub fn needs_refresh(&self, name: &str) -> bool

Check if view needs refresh

pub fn refresh(&mut self, name: &str, data: Vec<u8>)

Refresh a view with new data

pub fn mark_stale(&mut self, table: &str)

Mark views depending on a table as stale

pub fn due_for_refresh(&self) -> Vec<String>

Get views needing periodic refresh

pub fn remove(&mut self, name: &str)

Remove a view

pub fn list(&self) -> Vec<&str>

List all view names

Trait Implementations

impl Default for MaterializedViewCache
