Struct Type

pub struct Type {
    pub array_element_type: Option<Option<Box<Type>>>,
    pub code: Option<String>,
    pub proto_type_fqn: Option<String>,
    pub struct_type: Option<StructType>,
    pub type_annotation: Option<String>,
}

Type indicates the type of a Cloud Spanner value, as might be stored in a table cell or returned from an SQL query.

This type is not used in any activity, and only used as part of another schema.

Fields

array_element_type: Option<Option<Box<Type>>>

If code == ARRAY, then array_element_type is the type of the array elements.

code: Option<String>

Required. The TypeCode for this type.

proto_type_fqn: Option<String>

If code == PROTO or code == ENUM, then proto_type_fqn is the fully qualified name of the proto type representing the proto/enum definition.

struct_type: Option<StructType>

If code == STRUCT, then struct_type provides type information for the struct’s fields.

type_annotation: Option<String>

The 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 can be mapped to different SQL types depending on the SQL dialect. 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.

Trait Implementations

impl Clone for Type

fn clone(&self) -> Type

Returns a copy of the value.

Formats the value using the given formatter.

impl Default for Type

fn default() -> Type

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Type

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.
