Implementations

impl PoolField

pub const ALL: &'static [PoolField]

All variants of this metric set, in canonical order.

Examples

use dynomite::stats::PoolField;
assert!(!PoolField::ALL.is_empty());

pub fn name(self) -> &'static str

Lower-case identifier as it appears in the JSON output.

Examples

use dynomite::stats::PoolField;
let name = PoolField::ALL[0].name();
assert!(!name.is_empty());

pub fn kind(self) -> StatsMetricType

Whether this metric is a counter, gauge, or timestamp.

Examples

use dynomite::stats::{PoolField, StatsMetricType};
let k = PoolField::ALL[0].kind();
assert!(matches!(k, StatsMetricType::Counter | StatsMetricType::Gauge | StatsMetricType::Timestamp));

pub fn description(self) -> &'static str

Human-readable description used by --describe-stats.

Examples

use dynomite::stats::PoolField;
let d = PoolField::ALL[0].description();
assert!(!d.is_empty());

pub fn index(self) -> usize

Index of this metric in the corresponding stats vector.

Examples

use dynomite::stats::PoolField;
assert_eq!(PoolField::ALL[0].index(), 0);

Trait Implementations

impl Clone for PoolField

fn clone(&self) -> PoolField

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PoolField

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

Formats the value using the given formatter.

impl Hash for PoolField

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for PoolField

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