Implementations§

impl DecimalValue

pub fn cast<T: NativeDecimalType>(&self) -> Option<T>

Cast self to T using the respective ToPrimitive method. If the value cannot be represented by T, None is returned.

pub fn decimal_dtype(&self) -> DecimalDType

Returns a reasonable precision and scale as a DecimalDType for the given DecimalValue.

Note that this is not the same as DecimalValue::decimal_type!!!

pub fn decimal_type(&self) -> DecimalType

Returns the DecimalType for the given DecimalValue.

Note that this is not the same as DecimalValue::decimal_dtype!!!

pub fn is_zero(&self) -> bool

Returns true if this decimal value is zero.

pub fn zero(decimal_type: &DecimalDType) -> Self

Returns the 0 value given the DecimalType.

pub fn fits_in_precision(&self, decimal_type: DecimalDType) -> bool

Check if this decimal value fits within the precision constraints of the given decimal type.

The precision defines the total number of significant digits that can be represented. The stored value (regardless of scale) must fit within the range defined by precision. For precision P, the maximum absolute stored value is 10^P - 1.

pub fn checked_add(&self, other: &Self) -> Option<Self>

Checked addition. Returns None on overflow.

pub fn checked_sub(&self, other: &Self) -> Option<Self>

Checked subtraction. Returns None on overflow.

pub fn checked_mul(&self, other: &Self) -> Option<Self>

Checked multiplication. Returns None on overflow.

pub fn checked_div(&self, other: &Self) -> Option<Self>

Checked division. Returns None on overflow or division by zero.
