Type of decimal scalar values.

This trait is implemented by native integer types that can be used to store decimal values.

Required Associated Constants

const DECIMAL_TYPE: DecimalType

The decimal value type corresponding to this native type.

const MAX_PRECISION: u8

The maximum precision supported by this decimal type.

const MAX_SCALE: i8

The maximum scale supported by this decimal type.

const MIN_BY_PRECISION: &'static [Self]

The minimum value for each precision supported by this decimal type. This is an array of length MAX_PRECISION + 1 where the ith element is the minimum value for a precision of i (including precision 0).

const MAX_BY_PRECISION: &'static [Self]

The maximum value for each precision supported by this decimal type. similar to MIN_BY_PRECISION.

Required Methods

fn downcast<V: DecimalTypeDowncast>(visitor: V) -> V::Output<Self>

Downcast the provided object to a type-specific instance.

fn upcast<V: DecimalTypeUpcast>(input: V::Input<Self>) -> V

Upcast a type-specific instance to a generic instance.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
