PostgreSQL specific methods present on text expressions.

Provided methods

fn ilike<T: AsExpression<Text>>(self, other: T) -> ILike<Self, T::Expression>

Creates a PostgreSQL ILIKE expression

Example

let starts_with_s = animals
    .select(species)
    .filter(name.ilike("s%").or(species.ilike("s%")))
    .get_results::<String>(&connection)?;
assert_eq!(vec!["spider"], starts_with_s);

fn not_ilike<T: AsExpression<Text>>(
    self,
    other: T
) -> NotILike<Self, T::Expression>

Creates a PostgreSQL NOT ILIKE expression

Example

let doesnt_start_with_s = animals
    .select(species)
    .filter(name.not_ilike("s%").and(species.not_ilike("s%")))
    .get_results::<String>(&connection)?;
assert_eq!(vec!["dog"], doesnt_start_with_s);
