Struct StorageResourceReport 

pub struct StorageResourceReport {
    pub memory_bytes: Option<u64>,
    pub pages: Option<u64>,
    pub io_read_bytes: Option<u64>,
    pub io_write_bytes: Option<u64>,
}

Process-local resource footprint a storage backend attributes to one session. Returned by store::traits::DeviceStore::resource_report.

Fields

memory_bytes: Option<u64>

Estimated process-local bytes the backend holds for this session (e.g. a SQLite page cache). Some(0) for backends whose data lives outside this process (Redis, other network stores).

pages: Option<u64>

Pages/entries currently backing the store, when known (SQLite: database page count). A size indicator, not part of the memory total.

io_read_bytes: Option<u64>

Bytes read from the backing store this session, if the backend counts it.

io_write_bytes: Option<u64>

Bytes written to the backing store this session, if the backend counts it.

Implementations

impl StorageResourceReport

pub fn total_bytes(&self) -> u64

Retained process memory this backend reports (0 when unknown). Excludes the cumulative I/O counters, which are throughput, not residency.
