Struct Event

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

Events record things that happened during a Span’s lifetime.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

name: Cow<'static, str>

The name of this event.

timestamp: SystemTime

The time at which this event occurred.

attributes: Vec<KeyValue>

Attributes that describe this event.

dropped_attributes_count: u32

The number of attributes that were above the configured limit, and thus dropped.

Implementations

impl Event

pub fn new<T>( name: T, timestamp: SystemTime, attributes: Vec<KeyValue>, dropped_attributes_count: u32, ) -> Event

where T: Into<Cow<'static, str>>,

Create new Event

pub fn with_name<T>(name: T) -> Event

where T: Into<Cow<'static, str>>,

Create new Event with a given name.

Trait Implementations

impl Clone for Event

fn clone(&self) -> Event

Returns a copy 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<(), Error>

Formats the value using the given formatter.

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.
