PostgreSQL specific methods present between CIDR/INET expressions

Provided methods

fn contains<T>(self, other: T) -> ContainsNet<Self, T> where
    T: AsExpression<Inet>, 
[src]

Creates a PostgreSQL >> expression.

This operator returns wether 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()))

let my_hosts = hosts.select(id)
    .filter(address.contains(IpNetwork::from_str("10.0.3.31").unwrap()))
    .load::<i32>(conn)?;
assert_eq!(vec![2], my_hosts);

fn contains_or_eq<T>(self, other: T) -> ContainsNetLoose<Self, T> where

    .filter(address.is_contained_by(IpNetwork::from_str("10.0.2.5/24").unwrap()))
    .load::<i32>(conn)?;
assert_eq!(my_hosts.len(), 0);

let my_hosts = hosts.select(id)
    .filter(address.is_contained_by(IpNetwork::from_str("10.0.3.31/23").unwrap()))
    .load::<i32>(conn)?;
assert_eq!(vec![1], my_hosts);

let my_hosts = hosts.select(id)
    .filter(address.is_contained_by(IpNetwork::from_str("10.0.3.31/22").unwrap()))
    .load::<i32>(conn)?;

This operator computes the bitwise OR between two network addresses.

Example

diesel::insert_into(hosts)
    .values(vec![address.eq(IpNetwork::from_str("10.0.2.3").unwrap())])
    .execute(conn)?;

let addr = hosts
    .select(address.or(IpNetwork::from_str("0.0.0.255").unwrap()))
    .first::<IpNetwork>(conn)?;
assert_eq!(addr, IpNetwork::from_str("10.0.2.255").unwrap());

fn diff<T>(self, other: T) -> DifferenceNet<Self, T> where
    T: AsExpression<Inet>, 
[src]

Creates a PostgreSQL - expression.

This operator substracts an address from an address to compute the distance between the two

Example

diesel::insert_into(hosts)
    .values(vec![address.eq(IpNetwork::from_str("10.0.2.53").unwrap())])
    .execute(conn)?;

let offset = hosts
    .select(address.diff(IpNetwork::from_str("10.0.2.42").unwrap()))
    .first::<i64>(conn)?;
assert_eq!(offset, 11);
