Struct StoredColumnsUsage 

#[non_exhaustive]
pub struct StoredColumnsUsage {
    pub is_query_accelerated: Option<bool>,
    pub base_table: Option<TableReference>,
    pub stored_columns_unused_reasons: Vec<StoredColumnsUnusedReason>,
    /* private fields */
}

Indicates the stored columns usage in the 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.

is_query_accelerated: Option<bool>

Specifies whether the query was accelerated with stored columns.

base_table: Option<TableReference>

Specifies the base table.

stored_columns_unused_reasons: Vec<StoredColumnsUnusedReason>

If stored columns were not used, explain why.

Implementations

impl StoredColumnsUsage

pub fn new() -> Self

Creates a new default instance.

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

where T: Into<bool>,

Sets the value of is_query_accelerated.

Example

let x = StoredColumnsUsage::new().set_is_query_accelerated(true);

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

where T: Into<bool>,

Sets or clears the value of is_query_accelerated.

Example

let x = StoredColumnsUsage::new().set_or_clear_is_query_accelerated(Some(false));
let x = StoredColumnsUsage::new().set_or_clear_is_query_accelerated(None::<bool>);

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

where T: Into<TableReference>,

Sets the value of base_table.

Example

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

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

where T: Into<TableReference>,

Sets or clears the value of base_table.

Example

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

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

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

Sets the value of stored_columns_unused_reasons.

Example

use google_cloud_bigquery_v2::model::stored_columns_usage::StoredColumnsUnusedReason;
let x = StoredColumnsUsage::new()
    .set_stored_columns_unused_reasons([
        StoredColumnsUnusedReason::default()/* use setters */,
        StoredColumnsUnusedReason::default()/* use (different) setters */,
    ]);
