2Q (Two-Queue) cache metrics.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

Trait Implementations

impl Clone for TwoQMetricsSnapshot

fn clone(&self) -> TwoQMetricsSnapshot

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TwoQMetricsSnapshot

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

Formats the value using the given formatter.

impl Default for TwoQMetricsSnapshot

fn default() -> TwoQMetricsSnapshot

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for TwoQMetricsSnapshot

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<W: Write + Send> MetricsExporter<TwoQMetricsSnapshot> for PrometheusTextExporter<W>

fn export(&self, snapshot: &TwoQMetricsSnapshot)

impl<K, V> MetricsSnapshotProvider<TwoQMetricsSnapshot> for TwoQCore<K, V>

where K: Clone + Eq + Hash,

Available on crate feature metrics only.

fn snapshot(&self) -> TwoQMetricsSnapshot

impl PartialEq for TwoQMetricsSnapshot

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for TwoQMetricsSnapshot
