Provided Methods§
sourcefn contains<T>(self, other: T) -> ContainsNet<Self, T>where
T: AsExpression<Inet>,
fn contains<T>(self, other: T) -> ContainsNet<Self, T>where
T: AsExpression<Inet>,
Creates a PostgreSQL >>
expression.
This operator returns whether a subnet strictly contains another subnet or address.
§Example
diesel::insert_into(hosts)
.values(vec![address.eq(IpNetwork::from_str("10.0.2.3/24").unwrap()),
address.eq(IpNetwork::from_str("10.0.3.4/23").unwrap())])
.execute(conn)?;
let my_hosts = hosts.select(id)
.filter(address.contains(IpNetwork::from_str("10.0.2.5").unwrap()))
.load::<i32>(conn)?;
assert_eq!(vec![1, 2], my_hosts);
let my_hosts = hosts.select(id)
.filter(address.contains(IpNetwork::from_str("10.0.2.5/24").unwrap()))
.load::<i32>(conn)?;
assert_eq!(vec![2], my_hosts);
let my_hosts = hosts.select(id)
