Function prometheus::exponential_buckets [−][src]
pub fn exponential_buckets(
start: f64,
factor: f64,
count: usize
) -> Result<Vec<f64>>
Create count
buckets, where the lowest bucket has an
upper bound of start
and each following bucket’s upper bound is factor
times 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.
