assert_eq!(PreparedPlanCacheStats::default().entries, 0);

Fields

entries: usize

Retained terminal entries.

retained_bytes: usize

Logical bytes retained by entries, active attempts, and queued records.

hits: u64

Ready or redirect cache hits.

misses: u64

Distinct producer starts.

waits: u64

Waits on an existing active or queued key.

negative_hits: u64

Hits on retained deterministic failures.

preparations: u64

Producer callbacks invoked.

evictions: u64

Retained entries evicted by entry or byte limits.

redirects: u64

Redirect terminals returned.

in_flight: usize

Active distinct producer count.

peak_in_flight: usize

Highest observed active producer count.

queued_distinct_keys: usize

Distinct queued keys.

capacity_refusals: u64

Capacity refusals.

Trait Implementations

impl Clone for PreparedPlanCacheStats

fn clone(&self) -> PreparedPlanCacheStats

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PreparedPlanCacheStats

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

Formats the value using the given formatter.

impl Default for PreparedPlanCacheStats

fn default() -> PreparedPlanCacheStats

Returns the “default value” for a type.

impl PartialEq for PreparedPlanCacheStats

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

impl Copy for PreparedPlanCacheStats
