Struct zipkin::Annotation

pub struct Annotation { /* fields omitted */ }

An Annotation represents an occurence of an event at some time.

It consists of a timestamp, a string description of the event, and an optional Endpoint identifying the service in which the event ocurred. Annotations are attached to a Span.

Zipkin defines a number of "standard" event values:

• cs - "Client Sent": Generated by a client when it sends a request to a remote service.
• sr - "Server Receive": Generated by a server when it has received a request from a client.
• ss - "Server Sent": Generated by a server when it has finished processing a request and has sent the request back to the client.
• cr - "Client Receive": Generated by a client when it has received the server's response to a request.

Arbitrary user-defined values can also be used.
