Struct Event 

pub struct Event {
    pub time_unix_nano: u64,
    pub name: String,
    pub attributes: Vec<KeyValue>,
    pub dropped_attributes_count: u32,
}

Event is a time-stamped annotation of the span, consisting of user-supplied text description and key-value pairs.

Fields

time_unix_nano: u64

time_unix_nano is the time the event occurred.

name: String

name of the event. This field is semantically required to be set to non-empty string.

attributes: Vec<KeyValue>

attributes is a collection of attribute key/value pairs on the event. Attribute keys MUST be unique (it is not allowed to have more than one attribute with the same key).

The attribute values SHOULD NOT contain empty values. The attribute values SHOULD NOT contain bytes values. The attribute values SHOULD NOT contain array values different than array of string values, bool values, int values, double values. The attribute values SHOULD NOT contain kvlist values. The behavior of software that receives attributes containing such values can be unpredictable. These restrictions can change in a minor release. The restrictions take origin from the OpenTelemetry specification: https://github.com/open-telemetry/opentelemetry-specification/blob/v1.47.0/specification/common/README.md#attribute.

dropped_attributes_count: u32

dropped_attributes_count is the number of dropped attributes. If the value is 0, then no attributes were dropped.

Trait Implementations

impl Clone for Event

fn clone(&self) -> Event

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Event

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

Formats the value using the given formatter.

impl Default for Event

fn default() -> Self

Returns the “default value” for a type.

impl Message for Event

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 Event

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