Struct ForeignKey 

#[non_exhaustive]
pub struct ForeignKey {
    pub name: String,
    pub referenced_table: Option<TableReference>,
    pub column_references: Vec<ColumnReference>,
    /* private fields */
}

Represents a foreign key constraint on a table’s columns.

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.

name: String

Optional. Set only if the foreign key constraint is named.

referenced_table: Option<TableReference>

Required. The table that holds the primary key and is referenced by this foreign key.

column_references: Vec<ColumnReference>

Required. The columns that compose the foreign key.

Implementations

impl ForeignKey

pub fn new() -> Self

Creates a new default instance.

pub fn set_name<T: Into<String>>(self, v: T) -> Self

Sets the value of name.

Example

let x = ForeignKey::new().set_name("example");

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

where T: Into<TableReference>,

Sets the value of referenced_table.

Example

use google_cloud_bigquery_v2::model::TableReference;
let x = ForeignKey::new().set_referenced_table(TableReference::default()/* use setters */);

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

where T: Into<TableReference>,

Sets or clears the value of referenced_table.

Example

use google_cloud_bigquery_v2::model::TableReference;
let x = ForeignKey::new().set_or_clear_referenced_table(Some(TableReference::default()/* use setters */));
let x = ForeignKey::new().set_or_clear_referenced_table(None::<TableReference>);

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

where T: IntoIterator<Item = V>, V: Into<ColumnReference>,

Sets the value of column_references.

Example

use google_cloud_bigquery_v2::model::ColumnReference;
let x = ForeignKey::new()
    .set_column_references([
        ColumnReference::default()/* use setters */,
        ColumnReference::default()/* use (different) setters */,
    ]);
