Struct Range 

#[non_exhaustive]
pub struct Range<T: RangeElement> {
    pub start: Option<T>,
    pub end: Option<T>,
}

Represents a BigQuery RANGE value.

Example

use google_cloud_bigquery::client::BigQuery;
use google_cloud_bigquery::datatypes::Range;
use google_cloud_type::model::Date;

let client = BigQuery::builder()
    .with_project_id("my-project-id")
    .build()
    .await?;
let mut rows = client
    .query("SELECT RANGE(DATE '2024-01-01', DATE '2024-12-31') AS date_range")
    .until_done()
    .await?
    .read();

if let Some(row) = rows.next().await.transpose()? {
    let date_range: Range<Date> = row.get("date_range")?;
    println!("Start: {:?}, End: {:?}", date_range.start, date_range.end);
}

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.

start: Option<T>

The inclusive start of the range (or None if unbounded).

end: Option<T>

The exclusive end of the range (or None if unbounded).

Implementations

impl<T: RangeElement> Range<T>

pub fn new() -> Self

Creates a new unbounded range ([UNBOUNDED, UNBOUNDED)).

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

Sets the value of start.

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

Sets or clears the value of start.

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

Sets the value of end.

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

Sets or clears the value of end.

Trait Implementations
