Struct Annotation

pub struct Annotation { /* private fields */ }

Associates an event that explains latency with a timestamp.

Unlike log statements, annotations are often codes, e.g. “ws” for WireSend.

Zipkin v1 core annotations such as “cs” and “sr” have been replaced with Span::kind, which interprets timestamp and duration.

Implementations

impl Annotation

pub fn new(timestamp: SystemTime, value: &str) -> Annotation

pub fn now(value: &str) -> Annotation

Creates a new Annotation at the current time.

pub fn timestamp(&self) -> SystemTime

Returns the time at which the annotated event occurred.

pub fn value(&self) -> &str

Returns the value of the annotation.

impl Clone for Annotation

fn clone(&self) -> Annotation

Returns a duplicate of the value.

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