- 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.
- Array
Value - ArrayValue is a list of AnyValue messages. We need ArrayValue as a message since oneof in AnyValue does not allow repeated fields.
- Instrumentation
Scope - 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.
- KeyValue
List - KeyValueList is a list of KeyValue messages. We need KeyValueList as a message
since
oneofin AnyValue does not allow repeated fields. Everywhere else where we need a list of KeyValue messages (e.g. in Span) we userepeated KeyValuedirectly to avoid unnecessary extra wrapping (which slows down the protocol). The 2 approaches are semantically equivalent.
