Modules§

  • 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.
