Struct EntityRef 

pub struct EntityRef {
    pub schema_url: String,
    pub type: String,
    pub id_keys: Vec<String>,
    pub description_keys: Vec<String>,
}

A reference to an Entity. Entity represents an object of interest associated with produced telemetry: e.g spans, metrics, profiles, or logs.

Status: [Development]

Fields

schema_url: String

The Schema URL, if known. This is the identifier of the Schema that the entity data is recorded in. To learn more about Schema URL see https://opentelemetry.io/docs/specs/otel/schemas/#schema-url

This schema_url applies to the data in this message and to the Resource attributes referenced by id_keys and description_keys. TODO: discuss if we are happy with this somewhat complicated definition of what the schema_url applies to.

This field obsoletes the schema_url field in ResourceMetrics/ResourceSpans/ResourceLogs.

type: String

Defines the type of the entity. MUST not change during the lifetime of the entity. For example: “service” or “host”. This field is required and MUST not be empty for valid entities.

id_keys: Vec<String>

Attribute Keys that identify the entity. MUST not change during the lifetime of the entity. The Id must contain at least one attribute. These keys MUST exist in the containing {message}.attributes.

description_keys: Vec<String>

Descriptive (non-identifying) attribute keys of the entity. MAY change over the lifetime of the entity. MAY be empty. These attribute keys are not part of entity’s identity. These keys MUST exist in the containing {message}.attributes.

Trait Implementations

impl Clone for EntityRef

fn clone(&self) -> EntityRef

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EntityRef

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

Formats the value using the given formatter.

impl Default for EntityRef

fn default() -> Self

Returns the “default value” for a type.

impl Message for EntityRef

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 EntityRef

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