Implementations

impl CacheMetrics

pub fn new() -> Self

Create new cache metrics.

pub fn calculate_hit_rate(&mut self)

Calculate hit rate.

pub fn calculate_avg_latency(&mut self)

Calculate average latency.

pub fn estimate_bandwidth(&mut self, data_size_bytes: usize, time_secs: f64)

Estimate memory bandwidth usage.

Trait Implementations

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 Display for CacheMetrics

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

Formats the value using the given formatter.

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 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.
