Struct JoinRestrictionPolicy 

#[non_exhaustive]
pub struct JoinRestrictionPolicy {
    pub join_condition: Option<JoinCondition>,
    pub join_allowed_columns: Vec<String>,
    /* private fields */
}

Represents privacy policy associated with “join restrictions”. Join restriction gives data providers the ability to enforce joins on the ‘join_allowed_columns’ when data is queried from a privacy protected view.

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.

join_condition: Option<JoinCondition>

Optional. Specifies if a join is required or not on queries for the view. Default is JOIN_CONDITION_UNSPECIFIED.

join_allowed_columns: Vec<String>

Optional. The only columns that joins are allowed on. This field is must be specified for join_conditions JOIN_ANY and JOIN_ALL and it cannot be set for JOIN_BLOCKED.

Implementations

impl JoinRestrictionPolicy

pub fn new() -> Self

Creates a new default instance.

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

where T: Into<JoinCondition>,

Sets the value of join_condition.

Example

use google_cloud_bigquery_v2::model::join_restriction_policy::JoinCondition;
let x0 = JoinRestrictionPolicy::new().set_join_condition(JoinCondition::JoinAny);
let x1 = JoinRestrictionPolicy::new().set_join_condition(JoinCondition::JoinAll);
let x2 = JoinRestrictionPolicy::new().set_join_condition(JoinCondition::JoinNotRequired);

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

where T: Into<JoinCondition>,

Sets or clears the value of join_condition.

Example

use google_cloud_bigquery_v2::model::join_restriction_policy::JoinCondition;
let x0 = JoinRestrictionPolicy::new().set_or_clear_join_condition(Some(JoinCondition::JoinAny));
let x1 = JoinRestrictionPolicy::new().set_or_clear_join_condition(Some(JoinCondition::JoinAll));
let x2 = JoinRestrictionPolicy::new().set_or_clear_join_condition(Some(JoinCondition::JoinNotRequired));
let x_none = JoinRestrictionPolicy::new().set_or_clear_join_condition(None::<JoinCondition>);

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

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

Sets the value of join_allowed_columns.

Example

let x = JoinRestrictionPolicy::new().set_join_allowed_columns(["a", "b", "c"]);
