Struct google_api_proto::google::spanner::v1::Type

pub struct Type {
    pub code: i32,
    pub array_element_type: Option<Box<Type>>,
    pub struct_type: Option<StructType>,
    pub type_annotation: i32,
    pub proto_type_fqn: String,
}

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

Fields

code: i32

Required. The [TypeCode][google.spanner.v1.TypeCode] for this type.

array_element_type: Option<Box<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: Option<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: i32

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: String

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.

Implementations

impl Type

pub fn code(&self) -> TypeCode

Returns the enum value of code, or the default if the field is set to an invalid enum value.

pub fn set_code(&mut self, value: TypeCode)

Sets code to the provided enum value.

pub fn type_annotation(&self) -> TypeAnnotationCode

Returns the enum value of type_annotation, or the default if the field is set to an invalid enum value.

pub fn set_type_annotation(&mut self, value: TypeAnnotationCode)

Sets type_annotation to the provided enum value.

Trait Implementations

impl Clone for Type

fn clone(&self) -> Type

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Type

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Type

fn default() -> Self

Returns the “default value” for a type.

impl Message for Type

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge<B>(&mut self, buf: B) -> Result<(), DecodeError>

where B: Buf, Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited<B>(&mut self, buf: B) -> Result<(), DecodeError>

where B: Buf, Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for Type

fn eq(&self, other: &Type) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
