Struct Timed 

pub struct Timed { /* private fields */ }

A wrapper around a histogram that can time operations using a caller-provided clock.

Implementations

impl Timed

pub const fn new(histogram: Histogram) -> Self

Create a new timed histogram.

pub fn register<M: Metrics>( context: &M, name: &'static str, help: &'static str, ) -> Self

Register a duration histogram (see duration_histogram) wrapped for timing.

pub fn timer<C: Clock>(&self, clock: &C) -> Timer

Create a new timer that can record a duration from the current time.

pub async fn time_some<C: Clock, T>( &self, clock: &C, op: impl Future<Output = Option<T>>, ) -> Option<T>

Time an operation, recording a sample only if it resolves to Some.

impl Timed

pub fn scoped<C: Clock>(&self, clock: &Arc<C>) -> ScopedTimer<C>

Start a timer guard that observes the elapsed duration when dropped.

Trait Implementations

impl Clone for Timed

fn clone(&self) -> Timed

Returns a duplicate of the value.

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

Performs copy-assignment from source.
