TargetCompletedId.aspect
If empty, the id refers to the completion of the target. If not-empty, the id refers to the completion of an aspect applied to the (already completed) target.
For example, when building an apple_binary that depends on proto_library
”//:foo_proto”, there will be two TargetCompleted events for
”//:foo_proto”:
- An event with an empty aspect, corresponding to actions producing language-agnostic outputs from the proto_library; and
- An event with aspect “ObjcProtoAspect”, corresponding to Objective-C code generation.
TargetCompletedId.configuration
The configuration for which the target was built.
