Struct Buckets

pub struct Buckets {
    pub offset: i32,
    pub bucket_counts: Vec<u64>,
}

Available on crate features gen-tonic-messages and metrics only.

Buckets are a set of bucket counts, encoded in a contiguous array of counts.

Fields

offset: i32

Offset is the bucket index of the first entry in the bucket_counts array.

Note: This uses a varint encoding as a simple form of compression.

bucket_counts: Vec<u64>

bucket_counts is an array of count values, where bucket_counts[i] carries the count of the bucket at index (offset+i). bucket_counts[i] is the count of values greater than base^(offset+i) and less than or equal to base^(offset+i+1).

Note: By contrast, the explicit HistogramDataPoint uses fixed64. This field is expected to have many buckets, especially zeros, so uint64 has been selected to ensure varint encoding.

Trait Implementations

impl Clone for Buckets

fn clone(&self) -> Buckets

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Buckets

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

Formats the value using the given formatter.

impl Default for Buckets

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Buckets

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Message for Buckets

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 Buckets

fn eq(&self, other: &Buckets) -> 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.

impl Serialize for Buckets

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
