Struct StandardSqlDataType 

#[non_exhaustive]
pub struct StandardSqlDataType {
    pub type_kind: TypeKind,
    pub sub_type: Option<SubType>,
    /* private fields */
}

The data type of a variable such as a function argument. Examples include:

• INT64: {"typeKind": "INT64"}

• ARRAY<STRING>:

  { “typeKind”: “ARRAY”, “arrayElementType”: {“typeKind”: “STRING”} }

• STRUCT<x STRING, y ARRAY<DATE>>:

  { “typeKind”: “STRUCT”, “structType”: { “fields”: [ { “name”: “x”, “type”: {“typeKind”: “STRING”} }, { “name”: “y”, “type”: { “typeKind”: “ARRAY”, “arrayElementType”: {“typeKind”: “DATE”} } } ] } }

• RANGE<DATE>:

  { “typeKind”: “RANGE”, “rangeElementType”: {“typeKind”: “DATE”} }

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

type_kind: TypeKind

Required. The top level type of this field. Can be any GoogleSQL data type (e.g., “INT64”, “DATE”, “ARRAY”).

sub_type: Option<SubType>

For complex types, the sub type information.

Implementations

impl StandardSqlDataType

pub fn new() -> Self

Creates a new default instance.

pub fn set_type_kind<T: Into<TypeKind>>(self, v: T) -> Self

Sets the value of type_kind.

Example

use google_cloud_bigquery_v2::model::standard_sql_data_type::TypeKind;
let x0 = StandardSqlDataType::new().set_type_kind(TypeKind::Int64);
let x1 = StandardSqlDataType::new().set_type_kind(TypeKind::Bool);
let x2 = StandardSqlDataType::new().set_type_kind(TypeKind::Float64);

pub fn set_sub_type<T: Into<Option<SubType>>>(self, v: T) -> Self

Sets the value of sub_type.

Note that all the setters affecting sub_type are mutually exclusive.

Example

let x = StandardSqlDataType::new().set_sub_type(Some(
    google_cloud_bigquery_v2::model::standard_sql_data_type::SubType::ArrayElementType(StandardSqlDataType::default().into())));

pub fn array_element_type(&self) -> Option<&Box<StandardSqlDataType>>

The value of sub_type if it holds a ArrayElementType, None if the field is not set or holds a different branch.

pub fn set_array_element_type<T: Into<Box<StandardSqlDataType>>>( self, v: T, ) -> Self

Sets the value of sub_type to hold a ArrayElementType.

Note that all the setters affecting sub_type are mutually exclusive.

Example

let x = StandardSqlDataType::new().set_array_element_type(StandardSqlDataType::default()/* use setters */);
assert!(x.array_element_type().is_some());
assert!(x.struct_type().is_none());
assert!(x.range_element_type().is_none());

pub fn struct_type(&self) -> Option<&Box<StandardSqlStructType>>

The value of sub_type if it holds a StructType, None if the field is not set or holds a different branch.

pub fn set_struct_type<T: Into<Box<StandardSqlStructType>>>(self, v: T) -> Self

Sets the value of sub_type to hold a StructType.

Note that all the setters affecting sub_type are mutually exclusive.

Example

use google_cloud_bigquery_v2::model::StandardSqlStructType;
let x = StandardSqlDataType::new().set_struct_type(StandardSqlStructType::default()/* use setters */);
assert!(x.struct_type().is_some());
assert!(x.array_element_type().is_none());
assert!(x.range_element_type().is_none());

pub fn range_element_type(&self) -> Option<&Box<StandardSqlDataType>>

The value of sub_type if it holds a RangeElementType, None if the field is not set or holds a different branch.

pub fn set_range_element_type<T: Into<Box<StandardSqlDataType>>>( self, v: T, ) -> Self

Sets the value of sub_type to hold a RangeElementType.

Note that all the setters affecting sub_type are mutually exclusive.

Example

let x = StandardSqlDataType::new().set_range_element_type(StandardSqlDataType::default()/* use setters */);
assert!(x.range_element_type().is_some());
assert!(x.array_element_type().is_none());
assert!(x.struct_type().is_none());
