[−][src]Struct metrics_util::Quantile
A quantile that has both the raw value and a human-friendly display label.
We work with quantiles for optimal floating-point precison over percentiles, but most of the
time, monitoring systems show us percentiles, and usually in an abbreviated form: p99
.
On top of holding the quantile value, we calculate the familiar "p99" style of label, doing the
appropriate percentile conversion. Thus, if you have a quantile of 0.99
, the resulting label
is p99
, and if you have a quantile of 0.999
, the resulting label is p999
.
There are two special cases, where we label 0.0
and 1.0
as min
and max
, respectively.
Methods
impl Quantile
[src]
pub fn new(quantile: f64) -> Quantile
[src]
Creates a new Quantile
from a floating-point value.
All values are clamped between 0.0 and 1.0.
pub fn label(&self) -> &str
[src]
Gets the human-friendly display label.
pub fn value(&self) -> f64
[src]
Gets the raw quantile value.
