Struct GlobalStatsCache 

pub struct GlobalStatsCache { /* private fields */ }

Cached global statistics with automatic invalidation

This is the main entry point for getting global IDF values. It caches statistics and rebuilds them when the segment list changes.

Implementations

impl GlobalStatsCache

pub fn new() -> Self

Create a new cache

pub fn invalidate(&self)

Invalidate the cache (call when segments are added/removed/merged)

pub fn generation(&self) -> u64

Get current generation

pub fn get(&self) -> Option<Arc<GlobalStats>>

Get cached stats if valid, or None if needs rebuild

pub fn set(&self, stats: GlobalStats)

Update the cache with new stats

pub fn get_or_compute<F>(&self, compute: F) -> Arc<GlobalStats>

where F: FnOnce(&mut GlobalStatsBuilder),

Get or compute stats using the provided builder function (sync version)

For basic stats that don’t require async iteration.

pub fn needs_rebuild(&self) -> bool

Check if stats need to be rebuilt

pub fn set_stats(&self, stats: GlobalStats)

Set pre-built stats (for async computation)

Trait Implementations

impl Default for GlobalStatsCache

fn default() -> Self

Returns the “default value” for a type.
