any_value

Nested message and enum types in AnyValue.

Structs

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.
