Struct TableMetadataCacheUsage 

#[non_exhaustive]
pub struct TableMetadataCacheUsage {
    pub table_reference: Option<TableReference>,
    pub unused_reason: Option<UnusedReason>,
    pub explanation: Option<String>,
    pub staleness: Option<Duration>,
    pub table_type: String,
    pub pruning_stats: Option<PruningStats>,
    /* private fields */
}

Table level detail on the usage of metadata caching. Only set for Metadata caching eligible tables referenced 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.

table_reference: Option<TableReference>

Metadata caching eligible table referenced in the query.

unused_reason: Option<UnusedReason>

Reason for not using metadata caching for the table.

explanation: Option<String>

Free form human-readable reason metadata caching was unused for the job.

staleness: Option<Duration>

Duration since last refresh as of this job for managed tables (indicates metadata cache staleness as seen by this job).

table_type: String

Table type.

pruning_stats: Option<PruningStats>

The column metadata index pruning statistics.

Implementations

impl TableMetadataCacheUsage

pub fn new() -> Self

Creates a new default instance.

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

where T: Into<TableReference>,

Sets the value of table_reference.

Example

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

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

where T: Into<TableReference>,

Sets or clears the value of table_reference.

Example

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

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

where T: Into<UnusedReason>,

Sets the value of unused_reason.

Example

use google_cloud_bigquery_v2::model::table_metadata_cache_usage::UnusedReason;
let x0 = TableMetadataCacheUsage::new().set_unused_reason(UnusedReason::ExceededMaxStaleness);
let x1 = TableMetadataCacheUsage::new().set_unused_reason(UnusedReason::MetadataCachingNotEnabled);

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

where T: Into<UnusedReason>,

Sets or clears the value of unused_reason.

Example

use google_cloud_bigquery_v2::model::table_metadata_cache_usage::UnusedReason;

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

where T: Into<String>,

Sets the value of explanation.

Example

let x = TableMetadataCacheUsage::new().set_explanation("example");

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

where T: Into<String>,

Sets or clears the value of explanation.

Example

let x = TableMetadataCacheUsage::new().set_or_clear_explanation(Some("example"));
let x = TableMetadataCacheUsage::new().set_or_clear_explanation(None::<String>);

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

where T: Into<Duration>,

Sets the value of staleness.

Example

use wkt::Duration;
let x = TableMetadataCacheUsage::new().set_staleness(Duration::default()/* use setters */);

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

where T: Into<Duration>,

Sets or clears the value of staleness.

Example

use wkt::Duration;
let x = TableMetadataCacheUsage::new().set_or_clear_staleness(Some(Duration::default()/* use setters */));
let x = TableMetadataCacheUsage::new().set_or_clear_staleness(None::<Duration>);

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

Sets the value of table_type.

Example

let x = TableMetadataCacheUsage::new().set_table_type("example");

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

where T: Into<PruningStats>,

Sets the value of pruning_stats.

Example

use google_cloud_bigquery_v2::model::PruningStats;
let x = TableMetadataCacheUsage::new().set_pruning_stats(PruningStats::default()/* use setters */);

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

where T: Into<PruningStats>,

Sets or clears the value of pruning_stats.

Example

use google_cloud_bigquery_v2::model::PruningStats;
let x = TableMetadataCacheUsage::new().set_or_clear_pruning_stats(Some(PruningStats::default()/* use setters */));
let x = TableMetadataCacheUsage::new().set_or_clear_pruning_stats(None::<PruningStats>);
