pub struct BucketsView<T> { /* private fields */ }
Expand description

A view into a slice of metric buckets.

The view can be used to iterate over a large slice of metric data slicing even into the buckets themselves.

                   Full View
 /---------------------------------------------\
[[C:1], [C:12], [D:0, 1, 2, 3, 5, 5], [S:42, 75]]
 \--------------------------/  \---------------/
           View 1                    View 2

Iterating over a BucketsView yields BucketView items, only the first and last elements may be partial buckets.

In the above example View 1 has a partial bucket at the end and View 2 has a partial bucket in the beginning.

Using the above example, iterating over View 1 yields the buckets: [C:1], [C:12], [D:0, 1, 2, 3].

Implementations§
