Struct NumericMaxScale

pub struct NumericMaxScale(pub(crate) u8);

The max_scale of a SqlScalarType::Numeric.

This newtype wrapper ensures that the scale is within the valid range.

Tuple Fields

0: u8

Implementations

impl NumericMaxScale

pub const ZERO: NumericMaxScale

A max scale of zero.

pub fn into_u8(self) -> u8

Consumes the newtype wrapper, returning the inner u8.

Trait Implementations

impl Arbitrary for NumericMaxScale

type Parameters = <u8 as Arbitrary>::Parameters

The type of parameters that arbitrary_with accepts for configuration of the generated Strategy. Parameters must implement Default.

type Strategy = Map<<u8 as Arbitrary>::Strategy, fn(u8) -> NumericMaxScale>

The type of Strategy used to generate values of type Self.

fn arbitrary_with(_top: Self::Parameters) -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self). The strategy is passed the arguments given in args.

fn arbitrary() -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self).

impl Clone for NumericMaxScale

fn clone(&self) -> NumericMaxScale

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NumericMaxScale

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for NumericMaxScale

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for NumericMaxScale

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl MzReflect for NumericMaxScale

fn add_to_reflected_type_info(rti: &mut ReflectedTypeInfo)

Adds names and types of the fields of the struct or enum to rti.

impl Ord for NumericMaxScale

fn cmp(&self, other: &NumericMaxScale) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for NumericMaxScale

fn eq(&self, other: &NumericMaxScale) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for NumericMaxScale

fn partial_cmp(&self, other: &NumericMaxScale) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl RustType<ProtoNumericMaxScale> for NumericMaxScale

fn into_proto(&self) -> ProtoNumericMaxScale

Convert a Self into a Proto value.

fn from_proto( max_scale: ProtoNumericMaxScale, ) -> Result<Self, TryFromProtoError>

Consume and convert a Proto back into a Self value.

fn into_proto_owned(self) -> Proto

A zero clone version of Self::into_proto that types can optionally implement, otherwise, the default implementation delegates to Self::into_proto.

impl Serialize for NumericMaxScale

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<i64> for NumericMaxScale

type Error = InvalidNumericMaxScaleError

The type returned in the event of a conversion error.

fn try_from(max_scale: i64) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<usize> for NumericMaxScale

type Error = InvalidNumericMaxScaleError

The type returned in the event of a conversion error.

fn try_from(max_scale: usize) -> Result<Self, Self::Error>

Performs the conversion.
