Function prometheus::exponential_buckets
[−]
[src]
pub fn exponential_buckets(start: f64, factor: f64, count: usize) -> Result<Vec<f64>>
exponential_buckets
creates count
buckets, where the lowest bucket has an
upper bound of start
and each following buckets upper bound is
factortimes the previous bucket
s upper bound. The final +Inf bucket is not counted
and not included in the returned slice. The returned slice is meant to be
used for the Buckets field of HistogramOpts
.
The function returns an error if count
is zero, if start
is zero or
negative, or if factor
is less than or equal 1.
