Function diesel::pg::expression::dsl::numrange

pub fn numrange<lower, upper, bound>(
    lower: lower,
    upper: upper,
    bound: bound,
) -> numrange<lower, upper, bound>
where
    lower: AsExpression<Nullable<Numeric>>,
    upper: AsExpression<Nullable<Numeric>>,
    bound: AsExpression<RangeBoundEnum>,

Available on crate feature postgres_backend only.

Returns range of numeric values

Example

use diesel::dsl::numrange;
use diesel::pg::sql_types::RangeBound;

diesel::insert_into(posts)
    .values(&[
       versions.eq(numrange(Some(BigDecimal::from(3)), Some(BigDecimal::from(5)), RangeBound::LowerBoundInclusiveUpperBoundInclusive)),
       versions.eq(numrange(None, Some(BigDecimal::from(2)), RangeBound::LowerBoundInclusiveUpperBoundExclusive)),
    ]).execute(conn)?;

let cool_posts = posts.select(versions)
    .load::<(Bound<BigDecimal>, Bound<BigDecimal>)>(conn)?;
assert_eq!(vec![
         (Bound::Included(BigDecimal::from(3)), Bound::Included(BigDecimal::from(5))),
         (Bound::Unbounded, Bound::Excluded(BigDecimal::from(2))),
     ], cool_posts);
