Struct BucketsView

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

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

impl<T> BucketsView<T>

where T: AsRef<[Bucket]>,

pub fn new(buckets: T) -> Self

Creates a new buckets view containing all data from the slice.

pub fn len(&self) -> usize

Returns the amount of partial or full buckets in the view.

pub fn is_empty(&self) -> bool

Returns whether the view contains any buckets.

pub fn as_slice(&self) -> BucketsView<&[Bucket]>

Returns the same bucket view as a bucket view over a slice.

pub fn iter(&self) -> BucketsViewIter<'_>

Iterator over all buckets in the view.

pub fn by_size(self, size_in_bytes: usize) -> BucketsViewBySizeIter<T>

Iterator which slices the source view into segments with an approximate size of size_in_bytes.
