Classes
-
AnyValue
-
AnyValue is used to represent any type of attribute value. AnyValue may contain a
primitive value such as a string or integer or it may contain an arbitrary nested
object containing arrays, key-value lists and primitives.
-
ArrayValue
-
ArrayValue is a list of AnyValue messages. We need ArrayValue as a message
since oneof in AnyValue does not allow repeated fields.
-
InstrumentationScope
-
InstrumentationScope is a message representing the instrumentation scope information
such as the fully qualified name and version.
-
KeyValue
-
KeyValue is a key-value pair that is used to store Span attributes, Link
attributes, etc.
-
KeyValueList
-
KeyValueList is a list of KeyValue messages. We need KeyValueList as a message
since
oneof in AnyValue does not allow repeated fields. Everywhere else where we need
a list of KeyValue messages (e.g. in Span) we use repeated KeyValue directly to
avoid unnecessary extra wrapping (which slows down the protocol). The 2 approaches
are semantically equivalent.
