Attributes
Name	Description
`code`	`google.cloud.spanner_v1.types.TypeCode` Required. The `TypeCode][google.spanner.v1.TypeCode]` for this type.
`array_element_type`	`google.cloud.spanner_v1.types.Type` If `code][google.spanner.v1.Type.code]` == `ARRAY][google.spanner.v1.TypeCode.ARRAY]`, then `array_element_type` is the type of the array elements.
`struct_type`	`google.cloud.spanner_v1.types.StructType` If `code][google.spanner.v1.Type.code]` == `STRUCT][google.spanner.v1.TypeCode.STRUCT]`, then `struct_type` provides type information for the struct's fields.
`type_annotation`	`google.cloud.spanner_v1.types.TypeAnnotationCode` 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.
`proto_type_fqn`	`str` If `code][google.spanner.v1.Type.code]` == `PROTO][google.spanner.v1.TypeCode.PROTO]` or `code][google.spanner.v1.Type.code]` == `ENUM][google.spanner.v1.TypeCode.ENUM]`, then `proto_type_fqn` is the fully qualified name of the proto type representing the proto/enum definition.
