Examples

        name -> VarChar,
        location -> Point,
    }
}

    .returning(location)
    .execute(&connection)
    .unwrap();

    .select(location)
    .filter(location.is_contained_by(

fn clone(&self) -> Box

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Default for Box

fn default() -> Box

Returns the "default value" for a type.

impl Debug for Box

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl<'expr> AsExpression<Box> for &'expr PgBox

type Expression = Bound<Box, Self>

The expression being returned

fn as_expression(self) -> Self::Expression

Perform the conversion

impl<'expr2, 'expr> AsExpression<Box> for &'expr2 &'expr PgBox

impl SingleValue for Box

impl QueryId for Box

type QueryId = Box
