If [code][google.spanner.v1.Type.code] == [STRUCT][google.spanner.v1.TypeCode.STRUCT], then struct_type
provides type information for the struct's fields.
public TypeAnnotationCode TypeAnnotation { get; set; }
The [TypeAnnotationCode][google.spanner.v1.TypeAnnotationCode] that disambiguates SQL type that Spanner will
use to represent values of this type during query processing. This is
necessary for some type codes because a single [TypeCode][google.spanner.v1.TypeCode] can be mapped
to different SQL types depending on the SQL dialect. [type_annotation][google.spanner.v1.Type.type_annotation]
typically is not needed to process the content of a value (it doesn't
affect serialization) and clients can ignore it on the read path.
