Struct opentelemetry_proto::tonic::metrics::v1::Exemplar

pub struct Exemplar {
    pub filtered_attributes: Vec<KeyValue>,
    pub time_unix_nano: u64,
    pub span_id: Vec<u8>,
    pub trace_id: Vec<u8>,
    pub value: Option<Value>,
}

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

A representation of an exemplar, which is a sample input measurement. Exemplars also hold information about the environment when the measurement was recorded, for example the span and trace ID of the active span when the exemplar was recorded.

Fields

filtered_attributes: Vec<KeyValue>

The set of key/value pairs that were filtered out by the aggregator, but recorded alongside the original measurement. Only key/value pairs that were filtered out by the aggregator should be included

time_unix_nano: u64

time_unix_nano is the exact time when this exemplar was recorded

Value is UNIX Epoch time in nanoseconds since 00:00:00 UTC on 1 January 1970.

span_id: Vec<u8>

(Optional) Span ID of the exemplar trace. span_id may be missing if the measurement is not recorded inside a trace or if the trace is not sampled.

trace_id: Vec<u8>

(Optional) Trace ID of the exemplar trace. trace_id may be missing if the measurement is not recorded inside a trace or if the trace is not sampled.

value: Option<Value>

The value of the measurement that was recorded. An exemplar is considered invalid when one of the recognized value fields is not present inside this oneof.

Trait Implementations

impl Clone for Exemplar

fn clone(&self) -> Exemplar

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Exemplar

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

Formats the value using the given formatter.

impl Default for Exemplar

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Exemplar

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<T> From<&Exemplar<T>> for Exemplar

where T: Into<Value> + Copy,

fn from(ex: &SdkExemplar<T>) -> Self

Converts to this type from the input type.

impl Message for Exemplar

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 Exemplar

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for Exemplar

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
