Counters for one Residency::step window.

Fields

requests: u32

Wanted entries examined.

misses: u32

Of those, entries not resident.

prefetch_requests: u32

Wanted entries of class lead or lower.

issued: u32

Reads issued to the transport.

pending_loads: u32

Wanted entries whose bytes are read, landing or installing.

adopted: u32

Wanted entries that were already in flight or landed though nothing wanted them last window: their work was adopted, not repeated.

promoted: u32

In-flight requests promoted to a more urgent class.

cancelled: u32

In-flight requests cancelled to make way for a demand.

evictions: u32

Resources evicted.

failed_loads: u32

Reads and installs that failed since the previous window.

protected_full: u32

Requests that found no room even after evicting every allowed victim.

transport_full: u32

Times issuing stopped because the transport was full.

deferred: u32

Requests skipped because the CPU budget ran out.

backoff_skipped: u32

Misses skipped because the resource is inside its retry backoff.

unknown_keys: u32

Wanted keys the host does not know.

unconfigured: u32

Wanted keys whose category is not configured.

over_budget: u32

Requests that exceed their category’s page budget outright.

table_full: u32

Requests dropped because the entry table was full.

wanted_dropped: u32

Wanted entries beyond the table capacity, ignored.

eviction_overflow: u32

Requests held back because the eviction report buffer was too small.

compactions: u32

Runs moved by compaction.

pages_moved: u32

Pages moved by compaction.

work_used: u32

Bookkeeping work units spent (see the crate docs).

Trait Implementations

impl Clone for WindowStats

fn clone(&self) -> WindowStats

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WindowStats

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

Formats the value using the given formatter.

impl Default for WindowStats

fn default() -> WindowStats

Returns the “default value” for a type.

impl PartialEq for WindowStats

fn eq(&self, other: &WindowStats) -> 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.
