pub struct Histogram {
core: Arc<HistogramCore>,
}metrics only.Expand description
A Metric counts individual observations from an event or sample stream
in configurable buckets. Similar to a Summary,
it also provides a sum of observations and an observation count.
On the Prometheus server, quantiles can be calculated from a Histogram using
the histogram_quantile function in the query language.
Note that Histograms, in contrast to Summaries, can be aggregated with the
Prometheus query language (see the prometheus documentation for
detailed procedures). However, Histograms require the user to pre-define
suitable buckets, (see linear_buckets and exponential_buckets for
some helper provided here) and they are in general less accurate. The
Observe method of a Histogram has a very low performance overhead in
comparison with the Observe method of a Summary.

Source§fn fg(&self, value: Color) -> Painted<&T>
fn fg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self with the foreground set to
value.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like red() and
green(), which have the same functionality but are
pithier.
§Example
Set foreground color to white using fg():
use yansi::{Paint, Color};
painted.fg(Color::White);Set foreground color to white using white().
use yansi::Paint;
painted.white();Source§fn bright_black(&self) -> Painted<&T>

Source§fn bg(&self, value: Color) -> Painted<&T>
fn bg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self with the background set to
value.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like on_red() and
on_green(), which have the same functionality but
are pithier.
§Example
Set background color to red using fg():
use yansi::{Paint, Color};
painted.bg(Color::Red);Set background color to red using on_red().

Source§fn attr(&self, value: Attribute) -> Painted<&T>
fn attr(&self, value: Attribute) -> Painted<&T>
Enables the styling Attribute value.
This method should be used rarely. Instead, prefer to use
attribute-specific builder methods like bold() and
underline(), which have the same functionality
but are pithier.
§Example
Make text bold using attr():
use yansi::{Paint, Attribute};
painted.attr(Attribute::Bold);Make text bold using using bold().
use yansi::Paint;
painted.bold();Source§fn rapid_blink(&self) -> Painted<&T>

Source§fn quirk(&self, value: Quirk) -> Painted<&T>
fn quirk(&self, value: Quirk) -> Painted<&T>
Enables the yansi Quirk value.
This method should be used rarely. Instead, prefer to use quirk-specific
builder methods like mask() and
wrap(), which have the same functionality but are
pithier.
§Example
Enable wrapping using .quirk():
use yansi::{Paint, Quirk};
painted.quirk(Quirk::Wrap);Enable wrapping using wrap().
use yansi::Paint;
painted.wrap();Source§fn clear(&self) -> Painted<&T>
👎Deprecated since 1.0.1: renamed to resetting() due to conflicts with Vec::clear().

fn whenever(&self, value: Condition) -> Painted<&T>
Conditionally enable styling based on whether the Condition value
applies. Replaces any previous condition.
See the crate level docs for more details.
§Example
Enable styling painted only when both stdout and stderr are TTYs:
