Struct Real 

pub struct Real;

REAL storage class: a 64-bit float.

Trait Implementations

impl AggregatePolicy<SQLiteDialect> for Real

type Sum = Real

Result type of SUM.

type Avg = Real

Result type of AVG.

impl ArithmeticOutput for Real

type Output = Real

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<Any> for Real

type Output = Any

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<Integer> for Real

type Output = Real

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<Numeric> for Real

type Output = Real

The resulting SQL type of the arithmetic expression.
