Trait Implementations

impl ArithmeticOutput for Int4

type Output = Int4

The resulting SQL type of the arithmetic expression.

type Nullability = PropagateNullability

Whether the operator itself can produce NULL even from non-NULL operands: / and % on SQLite’s Integer, Real and Numeric and on every MySQL numeric type, which return NULL for a zero divisor. PostgreSQL raises an error instead, so its operators only propagate operand nullability.

impl ArithmeticOutput<Float4> for Int4

type Output = Float8

The resulting SQL type of the arithmetic expression.

type Nullability = PropagateNullability

Whether the operator itself can produce NULL even from non-NULL operands: / and % on SQLite’s Integer, Real and Numeric and on every MySQL numeric type, which return NULL for a zero divisor. PostgreSQL raises an error instead, so its operators only propagate operand nullability.

impl ArithmeticOutput<Float8> for Int4

type Output = Float8

The resulting SQL type of the arithmetic expression.

type Nullability = PropagateNullability

Whether the operator itself can produce NULL even from non-NULL operands: / and % on SQLite’s Integer, Real and Numeric and on every MySQL numeric type, which return NULL for a zero divisor. PostgreSQL raises an error instead, so its operators only propagate operand nullability.

impl ArithmeticOutput<Int2> for Int4

type Output = Int4
