Struct MetricsData

pub struct MetricsData {
    pub resource_metrics: Vec<ResourceMetrics>,
}

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

MetricsData represents the metrics data that can be stored in a persistent storage, OR can be embedded by other protocols that transfer OTLP metrics data but do not implement the OTLP protocol.

MetricsData └─── ResourceMetrics ├── Resource ├── SchemaURL └── ScopeMetrics ├── Scope ├── SchemaURL └── Metric ├── Name ├── Description ├── Unit └── data ├── Gauge ├── Sum ├── Histogram ├── ExponentialHistogram └── Summary

The main difference between this message and collector protocol is that in this message there will not be any “control” or “metadata” specific to OTLP protocol.

When new fields are added into this message, the OTLP request MUST be updated as well.

Fields

resource_metrics: Vec<ResourceMetrics>

An array of ResourceMetrics. For data coming from a single resource this array will typically contain one element. Intermediary nodes that receive data from multiple origins typically batch the data before forwarding further and in that case this array will contain multiple elements.

Trait Implementations

impl Clone for MetricsData

fn clone(&self) -> MetricsData

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MetricsData

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

Formats the value using the given formatter.

impl Default for MetricsData

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for MetricsData

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Message for MetricsData

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 MetricsData

fn eq(&self, other: &MetricsData) -> 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 MetricsData

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
