Enum TimeUnit 

#[non_exhaustive]
pub enum TimeUnit {
    Nanoseconds,
    Microseconds,
    Milliseconds,
    Seconds,
    Minutes,
    Hours,
    Days,
}

A subset of java.util.concurrent.TimeUnit used by the metrics rate stats.

A JDK type, so Kafka’s audience rules do not apply: it is public because the public MetricConfig::set_time_window, Rate and Meter take it.

Only the variants the metrics framework needs are modelled; the conversion factors used by the rate stats are exactly Java’s TimeUnit semantics.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Nanoseconds

Nanoseconds.

Microseconds

Microseconds.

Milliseconds

Milliseconds.

Seconds

Seconds.

Minutes

Minutes.

Hours

Hours.

Days

Days.

Implementations

impl TimeUnit

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

The name() of the unit, matching Java’s enum constant name.

pub fn to_millis(self, window: i64) -> i64

Convert a duration expressed in this unit to milliseconds, mirroring TimeUnit.MILLISECONDS.convert(window, unit). Integer truncation matches Java’s long arithmetic.

Trait Implementations

impl Clone for TimeUnit

fn clone(&self) -> TimeUnit

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TimeUnit

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

Formats the value using the given formatter.

impl PartialEq for TimeUnit

fn eq(&self, other: &TimeUnit) -> 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 Copy for TimeUnit

impl Eq for TimeUnit

impl StructuralPartialEq for TimeUnit
