Struct Event

pub struct Event {
    pub name: Cow<'static, str>,
    pub timestamp: SystemTime,
    pub attributes: Vec<KeyValue>,
    pub dropped_attributes_count: u32,
}

Available on crate feature trace only.

A Span has the ability to add events. Events have a time associated with the moment when they are added to the Span.

Fields

name: Cow<'static, str>

Event name

timestamp: SystemTime

Event timestamp

attributes: Vec<KeyValue>

Event attributes

dropped_attributes_count: u32

Number of dropped attributes

Implementations

impl Event

pub fn new<T: Into<Cow<'static, str>>>( name: T, timestamp: SystemTime, attributes: Vec<KeyValue>, dropped_attributes_count: u32, ) -> Self

Create new Event

pub fn with_name<T: Into<Cow<'static, str>>>(name: T) -> Self

Create new Event with a given name.

Trait Implementations

impl Clone for Event

fn clone(&self) -> Event

Returns a duplicate of the value.

const 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<'de> Deserialize<'de> for Event

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Event

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

Tests for self and other values to be equal, and is used by ==.

const 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 Event

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
