Struct MemoryManager 

pub struct MemoryManager { /* private fields */ }

Memory manager: the retained public stats shell over the real B1 cache.

It holds an optional handle to the shared DecompressedChunkCache. When present (the production path — MemoryManager::with_chunk_cache), stats reports that cache’s real activity. When absent (new, used where no cache is wired), the block-cache numbers report zero.

Implementations

impl MemoryManager

pub fn new(_config: &Config) -> Result<Self>

Create a memory manager not wired to a cache.

Retained for callers (and tests) that construct a manager without a live storage engine; its stats reports zero block-cache activity. Production opens use with_chunk_cache.

pub fn with_chunk_cache(chunk_cache: Arc<DecompressedChunkCache>) -> Self

Create a memory manager whose stats surface reports the real activity of the shared B1 decompressed-chunk cache (issue #1568).

pub fn stats(&self) -> Result<MemoryStats>

Get memory statistics.

The block-cache hit/miss counts and occupancy (total_memory_used) are sourced from the live B1 DecompressedChunkCache when wired (issue #1568): hit_count() / miss_count() / resident_bytes(). The retained row-cache and buffer-pool sub-fields report a fixed 0 — the richer honest surface is Epic B / B5. The -> Result<MemoryStats> signature is preserved for semver compatibility with Database::stats().

Trait Implementations

impl Debug for MemoryManager

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

Formats the value using the given formatter.
