• optional google.protobuf.Any optimization = 1

  An optimization is helpful information that don't influence semantics. May be ignored by a consumer.

• optional google.protobuf.Any enhancement = 2

  An enhancement alter semantics. Cannot be ignored by a consumer.

Describes a mapping between a specific extension entity and the uri where that extension can be found.

• uint32 extension_uri_reference = 1

  references the extension_uri_anchor defined for a specific extension URI.

• uint32 function_anchor = 2

  A surrogate key used in the context of a single plan to reference a specific function

• string name = 3

  A simple name if there is only one impl for the function within the YAML. A compound name, referencing that includes type short names if there is more than one impl per name in the YAML.
