Struct CacheMetrics 

pub struct CacheMetrics {
    pub hits: u64,
    pub misses: u64,
    pub hit_rate: f64,
    pub size: u64,
    pub capacity: u64,
    pub evictions: u64,
}

Plan cache metrics.

Fields

hits: u64

Cache hits.

misses: u64

Cache misses.

hit_rate: f64

Hit rate (0.0 - 1.0).

size: u64

Current number of cached plans.

capacity: u64

Maximum cache capacity.

evictions: u64

Number of evictions.

Implementations

impl CacheMetrics

pub fn new( hits: u64, misses: u64, size: u64, capacity: u64, evictions: u64, ) -> Self

Create new cache metrics.

Trait Implementations

impl Archive for CacheMetrics

where u64: Archive, f64: Archive,

const COPY_OPTIMIZATION: CopyOptimization<Self>

An optimization flag that allows the bytes of this type to be copied directly to a writer instead of calling serialize.

type Archived = ArchivedCacheMetrics

The archived representation of this type.

type Resolver = CacheMetricsResolver

The resolver for this type. It must contain all the additional information from serializing needed to make the archived type from the normal type.

fn resolve(&self, resolver: Self::Resolver, out: Place<Self::Archived>)

Creates the archived version of this value at the given position and writes it to the given output.

impl Clone for CacheMetrics

fn clone(&self) -> CacheMetrics

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CacheMetrics

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

Formats the value using the given formatter.

impl Default for CacheMetrics

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for CacheMetrics

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<__D: Fallible + ?Sized> Deserialize<CacheMetrics, __D> for Archived<CacheMetrics>

where u64: Archive, <u64 as Archive>::Archived: Deserialize<u64, __D>, f64: Archive, <f64 as Archive>::Archived: Deserialize<f64, __D>,

fn deserialize( &self, deserializer: &mut __D, ) -> Result<CacheMetrics, <__D as Fallible>::Error>

Deserializes using the given deserializer

impl PartialEq for CacheMetrics

fn eq(&self, other: &CacheMetrics) -> 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<__S: Fallible + ?Sized> Serialize<__S> for CacheMetrics

where u64: Serialize<__S>, f64: Serialize<__S>,

fn serialize( &self, serializer: &mut __S, ) -> Result<<Self as Archive>::Resolver, <__S as Fallible>::Error>

Writes the dependencies for the object and returns a resolver that can create the archived type.

impl Serialize for CacheMetrics

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
