Struct ChunkCacheStats 

pub struct ChunkCacheStats { /* private fields */ }

A read-only snapshot of a dataset’s chunk-cache occupancy.

Returned by crate::Dataset::chunk_cache_stats. Use it to confirm a chunk-cache configuration is taking effect: after reading a chunked dataset, an enabled cache reports a loaded index and retained chunks, a disabled one (or one over its byte/slot budget) reports fewer or none. The counts are a point-in-time view and change as further reads populate or evict chunks.

Implementations

impl ChunkCacheStats

pub const fn index_loaded(&self) -> bool

Whether the parsed chunk index is currently held in memory.

pub const fn cached_chunks(&self) -> usize

Number of decompressed chunks currently retained.

pub const fn cached_bytes(&self) -> usize

Total bytes of decompressed chunk data currently retained.

Trait Implementations

impl Clone for ChunkCacheStats

fn clone(&self) -> ChunkCacheStats

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ChunkCacheStats

impl Debug for ChunkCacheStats

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

Formats the value using the given formatter.

impl Default for ChunkCacheStats

fn default() -> ChunkCacheStats

Returns the “default value” for a type.

impl Eq for ChunkCacheStats

impl PartialEq for ChunkCacheStats

fn eq(&self, other: &ChunkCacheStats) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
