Struct TableConstraints 

#[non_exhaustive]
pub struct TableConstraints {
    pub primary_key: Option<PrimaryKey>,
    pub foreign_keys: Vec<ForeignKey>,
    /* private fields */
}

The TableConstraints defines the primary key and foreign key.

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.

primary_key: Option<PrimaryKey>

Optional. Represents a primary key constraint on a table’s columns. Present only if the table has a primary key. The primary key is not enforced.

foreign_keys: Vec<ForeignKey>

Optional. Present only if the table has a foreign key. The foreign key is not enforced.

Implementations

impl TableConstraints

pub fn new() -> Self

Creates a new default instance.

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

where T: Into<PrimaryKey>,

Sets the value of primary_key.

Example

use google_cloud_bigquery_v2::model::PrimaryKey;
let x = TableConstraints::new().set_primary_key(PrimaryKey::default()/* use setters */);

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

where T: Into<PrimaryKey>,

Sets or clears the value of primary_key.

Example

use google_cloud_bigquery_v2::model::PrimaryKey;
let x = TableConstraints::new().set_or_clear_primary_key(Some(PrimaryKey::default()/* use setters */));
let x = TableConstraints::new().set_or_clear_primary_key(None::<PrimaryKey>);

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

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

Sets the value of foreign_keys.

Example

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