Query-related metrics.

Fields

total_count: u64

Total queries executed.

avg_duration_us: u64

Average query time in microseconds.

p50_duration_us: u64

P50 (median) query time in microseconds.

p99_duration_us: u64

P99 query time in microseconds.

max_duration_us: u64

Maximum query time in microseconds.

by_entity: Vec<EntityQueryCount>

Queries per entity type.

Implementations

impl QueryMetrics

pub fn new( total_count: u64, avg_duration_us: u64, p50_duration_us: u64, p99_duration_us: u64, max_duration_us: u64, ) -> Self

Create new query metrics.

pub fn with_entity_count(self, entity: impl Into<String>, count: u64) -> Self

Add entity query count.

Trait Implementations

impl Archive for QueryMetrics

where u64: Archive, Vec<EntityQueryCount>: 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 = ArchivedQueryMetrics

The archived representation of this type.

type Resolver = QueryMetricsResolver

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 QueryMetrics

fn clone(&self) -> QueryMetrics

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QueryMetrics

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

Formats the value using the given formatter.

impl Default for QueryMetrics

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for QueryMetrics

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<QueryMetrics, __D> for Archived<QueryMetrics>

where u64: Archive, <u64 as Archive>::Archived: Deserialize<u64, __D>, Vec<EntityQueryCount>: Archive, <Vec<EntityQueryCount> as Archive>::Archived: Deserialize<Vec<EntityQueryCount>, __D>,

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

Deserializes using the given deserializer

impl PartialEq for QueryMetrics

fn eq(&self, other: &QueryMetrics) -> 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 QueryMetrics

where u64: Serialize<__S>, Vec<EntityQueryCount>: 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 QueryMetrics

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
