Struct tracing_timing::Builder

pub struct Builder<NH, S = ByName, E = ByMessage> { /* fields omitted */ }

Builder for TimingSubscriber instances.

This type implements the builder pattern. It lets you easily configure and construct a new TimingSubscriber subscriber. See the individual methods for details. To start, use [Builder::from]:

use tracing_timing::{Builder, Histogram};
let builder = Builder::from(|| Histogram::new(3).unwrap());
let subscriber = builder.build();

See the various new_* methods on Histogram for how to construct an appropriate histogram in the first place. All samples recorded by the subscriber returned from Builder::build will be recorded into histograms as returned by the provided constructor.

Methods

impl<NH, S, E> Builder<NH, S, E>

pub fn spans<S2>(self, span_group: S2) -> Builder<NH, S2, E>

Set the mechanism used to divide spans into groups.

See SpanGroup and the group module for details.

pub fn events<E2>(self, event_group: E2) -> Builder<NH, S, E2>

Set the mechanism used to divide events into per-span groups.

See EventGroup and the group module for details.

pub fn time(self, time: Clock) -> Builder<NH, S, E>

Set the time source to use for time measurements.

pub fn build(self) -> TimingSubscriber<NH, S, E> where
    S: SpanGroup,
    E: EventGroup,
    S::Id: Hash + Eq,
    E::Id: Hash + Eq,
    NH: FnMut() -> Histogram<u64>, 

Construct a TimingSubscriber as configured.
