Fields

sample_count: u64

sample_count_float: f64

Overrides sample_count if > 0.

sample_sum: f64

bucket: Vec<Bucket>

Buckets for the classic histogram.

Ordered in increasing order of upper_bound, +Inf bucket is optional.

start_timestamp: Option<Timestamp>

schema: i32

schema defines the bucket schema. Currently, valid numbers are -4 <= n <= 8. They are all for base-2 bucket schemas, where 1 is a bucket boundary in each case, and then each power of two is divided into 2^n logarithmic buckets. Or in other words, each bucket boundary is the previous boundary times 2^(2^-n). In the future, more bucket schemas may be added using numbers < -4 or > 8.

zero_threshold: f64

Breadth of the zero bucket.

zero_count: u64

Count in zero bucket.

zero_count_float: f64

Overrides sb_zero_count if > 0.

negative_span: Vec<BucketSpan>

Negative buckets for the native histogram.

negative_delta: Vec<i64>

Use either “negative_delta” or “negative_count”, the former for regular histograms with integer counts, the latter for float histograms.

Count delta of each bucket compared to previous one (or to zero for 1st bucket).

negative_count: Vec<f64>

Absolute count of each bucket.

positive_span: Vec<BucketSpan>

Positive buckets for the native histogram. Use a no-op span (offset 0, length 0) for a native histogram without any observations yet and with a zero_threshold of 0. Otherwise, it would be indistinguishable from a classic histogram.

positive_delta: Vec<i64>

Use either “positive_delta” or “positive_count”, the former for regular histograms with integer counts, the latter for float histograms.

Count delta of each bucket compared to previous one (or to zero for 1st bucket).

positive_count: Vec<f64>

Absolute count of each bucket.

exemplars: Vec<Exemplar>

Only used for native histograms. These exemplars MUST have a timestamp.

Trait Implementations

impl Clone for Histogram

fn clone(&self) -> Histogram

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Histogram

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Histogram

fn default() -> Self

Returns the “default value” for a type.

impl Message for Histogram

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for Histogram

fn eq(&self, other: &Histogram) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
