Struct SystemVariables 

#[non_exhaustive]
pub struct SystemVariables {
    pub types: HashMap<String, StandardSqlDataType>,
    pub values: Option<Struct>,
    /* private fields */
}

System variables given to a query.

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.

types: HashMap<String, StandardSqlDataType>

Output only. Data type for each system variable.

values: Option<Struct>

Output only. Value for each system variable.

Implementations

impl SystemVariables

pub fn new() -> Self

Creates a new default instance.

pub fn set_types<T, K, V>(self, v: T) -> Self

where T: IntoIterator<Item = (K, V)>, K: Into<String>, V: Into<StandardSqlDataType>,

Sets the value of types.

Example

use google_cloud_bigquery_v2::model::StandardSqlDataType;
let x = SystemVariables::new().set_types([
    ("key0", StandardSqlDataType::default()/* use setters */),
    ("key1", StandardSqlDataType::default()/* use (different) setters */),
]);

pub fn set_values<T>(self, v: T) -> Self

where T: Into<Struct>,

Sets the value of values.

Example

use wkt::Struct;
let x = SystemVariables::new().set_values(Struct::default()/* use setters */);

pub fn set_or_clear_values<T>(self, v: Option<T>) -> Self

where T: Into<Struct>,

Sets or clears the value of values.

Example

use wkt::Struct;
let x = SystemVariables::new().set_or_clear_values(Some(Struct::default()/* use setters */));
let x = SystemVariables::new().set_or_clear_values(None::<Struct>);
