The default read-only implementation of BinaryAnnotation.
The default read-only implementation of BinaryAnnotation. You typically should not need to directly reference this class; instead, use the BinaryAnnotation.apply method to construct new instances.
This Proxy trait allows you to extend the BinaryAnnotation trait with additional state or behavior and implement the read-only methods from BinaryAnnotation using an underlying instance.
Field information in declaration order.
Checks that all required fields are non-null.
Checks that the struct is a valid as a new instance.
Checks that the struct is a valid as a new instance. If there are any missing required or construction required fields, return a non-empty list.
Binary annotations are tags applied to a Span to give it context. For example, a binary annotation of "http.uri" could the path to a resource in a RPC call.
Binary annotations of type STRING are always queryable, though more a historical implementation detail than a structural concern.
Binary annotations can repeat, and vary on the host. Similar to Annotation, the host indicates who logged the event. This allows you to tell the difference between the client and server side of the same key. For example, the key "http.uri" might be different on the client and server side due to rewriting, like "/api/v1/myresource" vs "/myresource. Via the host field, you can see the different points of view, which often help in debugging.
