Struct GeneratedColumn 

#[non_exhaustive]
pub struct GeneratedColumn {
    pub generated_mode: Option<GeneratedMode>,
    pub definition: Option<Definition>,
    /* private fields */
}

Optional. Definition of how values are generated for the field. Only valid for top-level schema fields (not nested fields).

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.

generated_mode: Option<GeneratedMode>

Optional. Dictates when system generated values are used to populate the field.

definition: Option<Definition>

Captures the metadata for the generated column.

Implementations

impl GeneratedColumn

pub fn new() -> Self

Creates a new default instance.

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

where T: Into<GeneratedMode>,

Sets the value of generated_mode.

Example

use google_cloud_bigquery_v2::model::table_field_schema::generated_column::GeneratedMode;
let x0 = GeneratedColumn::new().set_generated_mode(GeneratedMode::GeneratedAlways);
let x1 = GeneratedColumn::new().set_generated_mode(GeneratedMode::GeneratedByDefault);

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

where T: Into<GeneratedMode>,

Sets or clears the value of generated_mode.

Example

use google_cloud_bigquery_v2::model::table_field_schema::generated_column::GeneratedMode;
let x0 = GeneratedColumn::new().set_or_clear_generated_mode(Some(GeneratedMode::GeneratedAlways));
let x1 = GeneratedColumn::new().set_or_clear_generated_mode(Some(GeneratedMode::GeneratedByDefault));
let x_none = GeneratedColumn::new().set_or_clear_generated_mode(None::<GeneratedMode>);

pub fn set_definition<T: Into<Option<Definition>>>(self, v: T) -> Self

Sets the value of definition.

Note that all the setters affecting definition are mutually exclusive.

Example

use google_cloud_bigquery_v2::model::table_field_schema::GeneratedExpressionInfo;
let x = GeneratedColumn::new().set_definition(Some(
    google_cloud_bigquery_v2::model::table_field_schema::generated_column::Definition::GeneratedExpressionInfo(GeneratedExpressionInfo::default().into())));

pub fn generated_expression_info(&self) -> Option<&Box<GeneratedExpressionInfo>>

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

pub fn set_generated_expression_info<T: Into<Box<GeneratedExpressionInfo>>>( self, v: T, ) -> Self

Sets the value of definition to hold a GeneratedExpressionInfo.

Note that all the setters affecting definition are mutually exclusive.

Example

use google_cloud_bigquery_v2::model::table_field_schema::GeneratedExpressionInfo;
let x = GeneratedColumn::new().set_generated_expression_info(GeneratedExpressionInfo::default()/* use setters */);
assert!(x.generated_expression_info().is_some());
