Struct Range

pub struct Range<ST: 'static>(/* private fields */);

Available on crate feature postgres_backend only.

The Range SQL type.

This wraps another type to represent a SQL range of that type.

ToSql impls

• (Bound<T>, Bound<T>) for any T which implements ToSql<ST>.
• Range<T> (aka start..end) for any T which implements ToSql<ST>.
• RangeInclusive<T> (aka start..=end) for any T which implements ToSql<ST>.
• RangeFrom<T> (aka start..) for any T which implements ToSql<ST>.
• RangeTo<T> (aka ..end) for any T which implements ToSql<ST>.
• RangeToInclusive<T> (aka ..=end) for any T which implements ToSql<ST>.

FromSql impls

• (Bound<T>, Bound<T>) for any T which implements FromSql<ST>.
